[freeglut] / ChangeLog

********** Hey Emacs, please use -*- fundamental -*- mode! **********

Changes to Freeglut:

Before and on October 22, 2002:

(1) Many trivial changes (changing floating-point numbers to integers, for example) to reduce the number of compiler warnings

(2) Removing "strlen" calls from for-loop headers to make things execute ever-so-slightly faster

(3) Slight changes to the "glutSolidSphere" and "glutWireSphere" functions to reduce the number of calls to the sine and cosine functions and otherwise make it slightly more efficient

(4) Added wire and solid torus, wire and solid dodecahedron, wire and solid octahedron, wire and solid tetrahedron, and wire and solid icosahedron

(5) Fixed a bug by which the GLUT menu now draws even when nothing else is happening in the window

(6) Fixed a bug by which freeglut now tracks which window text is being entered into

(7) Added code to adjust for the thickness of the window borders and header bar when resizing and repositioning a window

October 23, 2002:

(8) Added a window destroy callback for freeglut to call the application when a window is closed.  Made freeglut call "exit" if there is no window destroy callback.

October 24, 2002:

(8b)  Also started working on the code to implement the other behaviors when the user clicks on the "x" on the window header bar.

(9) Added the "glutSetOption" function, the "GLUT_ACTION_ON_WINDOW_CLOSE" enumeration, and its allowed values

(10) Added code to check whether a window is a subwindow in the reposition and reshape functions.  If it is a subwindow, do not adjust the position and size for the window border.

(11) Added code to fix the drawing of subwindows inside of windows.  The Windows implementation uses "GetWindowRect" which uses coordinates relative to the screen corner, not the parent window corner.

(12) Modified the code to open a window so that the freeglut window now matches the GLUT window.

(13) Added an ugly hack to the main loop function to call each window's visibility callback before jumping into the main loop.  This fixes the behaviour of several of the demo programs.



*******************************************************************************************
* Sent a copy of the files to Steve Baker 10/24/02.
*******************************************************************************************

(14) Reworked the "freeglut_font.c" file pretty thoroughly to speed things up a bit, to add the "glutStrokeString" function, and to make the "glutStrokeLength" function return an accurate value for long strings.  Also allowed the string functions to handle character strings containing carriage returns.

(15) Moved the "fgState" structure initialization in "freeglut_init.c" out of "fgInitialize" to set them at compile time.  Also added it to "fgDeinitialize" to reset the state.

(16) Recoded a bit in "glutInit" to speed things up slightly

(17) Added "#pragma warning ( once: 4305 )" directives to the stroke font files so that I don't get 4000 compiler warnings about assigning double precision constants to single precision variables

(18) Added a state enumeration (initializing, running, stopping) and flag to the "fgState" structure.  Modified the window closure and main loop code to use the enumeration instead of local variables.

(19) Fixed the "glutPositionWindow" so that if you get and retrieve the window position twenty times in a row the window won't slide down the screen.

(20) Recoded the "glut*Cone" functions so that they have normals on the curved surface and so that the "base" argument is really the radius of the base of the cone.

(21) Added code to render a rhombic dodecahedron in the geometry library.

(22) Started work on a "glutInitDisplayString" function.  I have provided a framework; I will need some serious help in interpreting the results.

(23) Modified the "fgDisplayMenu" so that the matrix mode is GL_MODELVIEW instead of GL_PROJECTION when execution returns to its calling function.  I have no idea why, but this fixes some display problems in some of the demos.  Part (or all) of the display was blanking out when the user brought up a menu.

(24) Added four "pragma comment" lines to "freeglut.h" so that freeglut will automatically (under Windows) include "winmm.lib", "opengl32.lib", "glu32.lib", and "freeglut.lib".  This way the application doesn't have to do this by hand.

(25) Fixed the window positioning code so that if the border is going to extend above the top of the screen, it gets set to the top of the screen.

(26) Added right-arrows to menu entries which have submenus.  Also modified the submenu position so that it comes down to the right or to the left of the parent menu.

(27) Recoded a good bit of the menu processing to make the menus behave more like GLUT menus.

*******************************************************************************************
* Sent a copy of the files to Steve Baker 10/31/02.  Also posted these on the reflector.
*******************************************************************************************

(28) Added parentheses to the Windows version of setting the "State.Modifiers" to allow for precedence of operators.  Also modified the code so that it follows the "getKeyState" return value specification.

(29) Made the window event handler check for the existence of a window for all messages except the "create" message

(30) Changed the order of events in the window closure function so that the window would still be in the windows structure when the closure message to Windows was sent.

(31) Made some more changes to the window closure code so that it works from both clicking on the "x" and from a "glutDestroyWindow" call

*******************************************************************************************
* Sent a copy of the files to Steve Baker 10/31/02 as an update.  Also posted these on the reflector.
*******************************************************************************************

(32) Added "glutLeaveMainLoop" function.

(33) Added "glutMainLoopEvent" function.  This processes a single iteration through the "glutMainLoop" and is (theoretically) usable for re-entrant GLUT code.

(34) Implemented the "WM_KEYUP" and "WM_SPECIALKEYUP" callbacks in the Windows version.

(35) Added normals to the "glutWireCube" function

(36) Recoded "glutGetExtension" to remove a <Steve, cover your eyes> "goto" statement </Steve, cover your eyes> from the code.

(37) Marked the "glutSetKeyRepeat" function as deprecated.

(38) Implemented most of the Windows version of the "fghGetConfig" function.

*******************************************************************************************
* Took up the project again November 19.
*******************************************************************************************

(39) Added two missing characters to each of the bitmapped fonts.

(40) Added "glutSierpinskiSponge" to the geometry file.  I can take it out if people object.

(41) Added a linked list of windows to close so that if you destroy a window from within its callback the program won't terminate on error.

(42) Added a call to "free" in the joystick code so we wouldn't have a memory leak.  Also fixed another memory leak.

(43) Fixed the bitmapped Helvetica 12 and Helvetica 18 fonts so they now match the GLUT fonts.

*******************************************************************************************
* Sent the files to Don Heyse on November 27 for inclusion in CVS.
*******************************************************************************************

(44) Fixed the other bitmapped fonts so they now match the GLUT fonts.  There are some differences in the placement of the bit patterns within the characters, but the greatest difference is only a pixel or two.

(45) Added DLL capability.  Changed the names of the outputs so that the static library is "freeglut_static.lib" and the names of the DLL file and its interface file are "freeglut.dll" and "freeglut.lib".

(46) Moved the "freeglut_internal.h" file from the public include directory to the private source code directory.

(47) Split the "freeglut.h" file into a "glut.h" file that is compatible with GLUT and a "freeglut_ext.h" file that contains the new extensions.

*******************************************************************************************
* Changes starting in May 2003
*******************************************************************************************

(48) Changed "freeglut_main.c" to allow the Windows version to pass the mouse position to the keystroke callbacks

(49) Changed "freeglut_main.c" in the Unix section to move the call to find the event's window to before the "switch" statement.

(50) Changed "freeglut_main.c" in the Unix section to modify the window closure sequence of events slightly.

(51) Changed "freeglut_state.c" so the "glutGet" calls with window position and size don't move the windows down and to the right one pixel.

(52) Implement single-buffered rendering (or its emulation) in Windows.

(53) Implement Eero Pajarre's "GLUT_ICON" code.

(54) Fixes for the window positioning problem.

(55) Fixed a couple of compiler warnings and other bugs. Changed "freeglut_main.c" to remove a compiler warning. Changed "freeglut_structure.c" to set the current window before calling the window closure callback.


*******************************************************************************************
* Changes on 17-19 June 2003
*******************************************************************************************

(56) Added glutGetProcAddress()

(57) Added GLUT_FPS env var.

(58) Implemented Aleksandar Donev's user data changes:  added user data fields to window and menu structures and implemented functions to get and set them

(59) Added a "MenuDestroy" callback which sets a function that "freeglut" calls when a menu is destroyed.

*******************************************************************************************
* Changes on 24 June 2003

*******************************************************************************************

(100) GameMode fixes: src/freeglut_gamemode.c src/freeglut_internal.h src/freeglut_window.c

  src/freeglut_gamemode.c:
     fghRememberState():     remember original XFree86 ViewPort

*******************************************************************************************
* Changes up to September 12, 2003
*******************************************************************************************

(101) Include files:  Underscores added to the defined constants which prevent multiple inclusions

(102) String functions:  Arguments changed from "char *" to "unsigned char *" for compatibility with GLUT

(103) Added several explicit type casts to allow compilation with "Dev C++" compiler

(104) Quite a bit of debugging of the menus in their menu windows

(105) Removed "glib" dependency from joystick code; now it compiles under FreeBSD

(106) Removed the "fgCleanUpGlutsMess" function because it was redundant


*******************************************************************************************
* Changes on September 13, 2003
*******************************************************************************************

(107) Repaired DOS line endings in the MSVC project and workspace files

(108) Fixed some relative paths in the MSVC demo project files

(109) Fixed all the demo makefiles to ensure they compiled properly; included minor changes to some of the sources.

(110) Fixed compiliation of freeglut_joystick.c on FreeBSD

*******************************************************************************************
* Changes through September 24, 2003
*******************************************************************************************

(111) Fixed busy-wait bug in freeglut; now sleeps when there's nothing to do.

(112) GLUT_SINGLE properly supported.

(113) progs/demos/Fractals_random works.

*******************************************************************************************
* Freeglut 2.0.0 Released on  September 29, 2003!
*******************************************************************************************

*******************************************************************************************
* Changes on October 1, 2003
*******************************************************************************************

(114) Support for more than 3 mouse-buttons (this allows 3+scroll-wheel to
workin X, for example).

(115) Added 3rd party patch to make joystick code work on NetBSD (untested)
and on older versions of FreeBSD (also untested)

*******************************************************************************************
* Changes on October 3, 2003
*******************************************************************************************

(116) Tweaking for the menu behavior on Linux regarding mice, etc. - John Fay

*******************************************************************************************
* Changes on October 6, 2003
*******************************************************************************************

(117) freeglut_menu.c:328 Fix submenu triangle (John Fay)

*******************************************************************************************
* Changes on October 8, 2003
*******************************************************************************************

(118) freeglut_menu.c:217,519,532: Fix menus to stay in the window (John Fay)

(119) Fixed menu callbacks to set the current window.

(120) Numerous GLUT-alikeness corrections made to the menus (UNIX_X11
freeglut menus now look more like old UNIX/X11 GLUT menus).  Placement
and highlighting of menus is greatly improved as well, and (at least
at compile-time) it is now easy to change fonts and colors for menus.

(121) Fixed CreateNotify on X11 to act like ConfigureNotify.  This
helps subwindows in freeglut behave more like top-level windows.  (In
old GLUT, they behaved essentially the same, so we try to reproduce
that here.)

*******************************************************************************************
* Changes on October 9, 2003
*******************************************************************************************

(122) Minor glutInit*() quibbles in some of the demos.  Also applied a
change from John so that the affine-transform demos would work even if
they couldn't find their default set of transforms or the one named on
the command-line (a simpler one than even the default is built in).

*******************************************************************************************
* Changes on October 11, 2003
*******************************************************************************************

(123) Disallow people to pass NULL in for glutDisplayFunc().

(124) More menu fixes from John.

(125) Check the memory allocation of timers.

(126) Some code style/readability issues.

*******************************************************************************************
* Changes on October 11, 2003
*******************************************************************************************

(127) Fleshed out all missing cursor types on NetBSD (UNIX_X11) for the
glutSetCursor() call.  GLUT_CURSOR_NONE still required work.  Fixes
included: Adding numerous types required by GLUT but previously missing
in freeglut, reversing the left/right glyphs, and some just-plain-wrong
glyphs corrected.

*******************************************************************************************
* Changes on October 13, 2003
*******************************************************************************************

(128) Removed obsolete hack (or ill-conceived dream) of fgDisplayCursor().

(129) Modified the the fractal demos so that they don't clear/redraw quite
so often.

(129) Code readability/style issues.

*******************************************************************************************
* Changes on October 14, 2003
*******************************************************************************************

(130) More style issues.

*******************************************************************************************
* Freeglut 2.0.1 Released on 23 October, 2003!
*******************************************************************************************

*******************************************************************************************
* Changes on October 26, 2003
*******************************************************************************************

(131) Made freeglut know the program's name (fetch from main()'s argv[0]).

(132) Moved idle callback out of glutMainLoopEvent().

(133) Committed Nigel's fix to make the joystick set the current window before
invoking the callback.  (Completes the closeout of an open bug report,
once verified.)

(134) Added some error-checking of memory allocations.

(135) More style issues.

*******************************************************************************************
* Changes on October 27, 2003
*******************************************************************************************

(136) Partially unified the UNIX_X11 and WIN32 branches of glutMainLoopEvent()

(137) Updated comments, other style issues.  Check for some NULL pointers.

*******************************************************************************************
* Changes on October 28, 2003
*******************************************************************************************

(138) More style issues.

(139) Mouse-wheel support added for WIN32.  API extension generally
added to freeglut.

*******************************************************************************************
* Changes on October 29, 2003
*******************************************************************************************

(140) Fixed a bug in fgWarning()/fgError().  Added range-check to
glutSetKeyRepeat().

(141) More style issues.

(142) Removed bogus references to "Linux" in freeglut_state.c.
The references should have properly been to UNIX and/or X11.  GNU/LINUX
emulates UNIX, and X11 is the windowing system that runs on most graphics-
capable UNIX systems (including most GNU/LINUX systems).  freeglut should
run on any sufficiently UNIX-like system with OpenGL and X11 (or at least
XFree86's implementation of X11).

(143) #include <sys/param.h> on the BSDs so that we can check the system
version number at compile-time.

*******************************************************************************************
* Changes on October 30, 2003
*******************************************************************************************

(144) Numerous small fixes w.r.t. mouse-wheels on WIN32.

(145) More style issues.

*******************************************************************************************
* Changes on October 31, 2003
*******************************************************************************************

(146) More style issues.

(147) Converted an error-check from an assert() to an if().

(148) Removal of the last ASCII TAB character from src/* files.  This
conversion process ensures that the formatting appears more consistant
for everyone.  (TABs can vary in their expansion from one system to
another).

*******************************************************************************************
* Changes on November 3, 2003
*******************************************************************************************

(149) X11 mousewheel fixes.

(150) Yet more style issues.

(151) Added a case for {MapNotify} events in X11.

(152) Re-(?)deleted 3 files from CVS, per John's request.  These were
obsolete: freeglut13.dsp, freeglutdll.dsp, freeglutstatic.dsw

(153) Marked a few pointer/int conversion warnings.  (I think that they
only manifest for me on my AMD64 system, but they seem fairly harmless
so I didn't try to fix them.)

(154) Memory-leak fix from John.

*******************************************************************************************
* Changes on Novembber 4, 2003
*******************************************************************************************

(155) More style issues.

(156) Removed G_LOG_DOMAIN junk, per mailing list discussion.

(157) Added memory-leak detection support (WIN32) to a couple of the
demos, and fixed at least one memory leak in the process.  Also
converted Fractals_random to double-precision to avoid some compiler
warnings.

(158) Stripped CRs from fractals_random.c.

(159) Fixed two bugs: Execution state was improperly set in the end
of glutMainLoop(), and {ButtonPress} (an X11 constant) was used where
the flag-variable {pressed} (in UNIX_X11 branch of glutMainLoop())
should have been used.

(160) Pointer-check before deallocation in the menu code.

*******************************************************************************************
* Changes on November 5, 2003
*******************************************************************************************

Remember, remember,
the 5th of November.
Gunpowder, treason and plot!   (Bacon?)

I see no reason
why gunpowder treason
should ever be forgot.         (Shakespeare?)

*******************************************************************************************
* Changes on November 6, 2003
*******************************************************************************************

(161) Fractals_random demo now includes mouse support---including mouse-
wheel.

(162) Yet more fixes to the mouse wheel support in WIN32.

(163) Converted freeglut to use an array to store window callbacks,
rather than a struct.  This lets us loop over the array to fill it with
NULL pointers in order to clear the callbacks.  (With a struct, we were
reduced to either a ton of assignments---easy to miss one!---or memset(),
which technically is not a legal way to fill a region with NULL pointers
because the bit-pattern of a NULL pointer is not necessarily defined to
be all-zero bits.)  This change also on the one hand provides macros
to simplify most proper use of the callbacks (even simpler than with
the struct form), while also making it irritating enough to bypass the
macros that (it is hoped) abuse will be harder.  (E.g., the invocation
macros set the current-window.  At least two bugs in the past occurred
because callbacks were not setting the current window before invoking the
client.)  See 
https://sourceforge.net/mailarchive/message.php?msg_id=6467923 for more
details.

(164) Yet more style issues.  (You thought I'd forgotten about that?)

*******************************************************************************************
* Changes on November 7, 2003
*******************************************************************************************

(165) Mouse-wheel corrections in X11.

(166) Style corrections.

(167) Fixed GLUT_CURSOR_NONE support at long last in NetBSD.  (Should also
apply to other X11 based systems, but I can only test NetBSD.)  Also
deallocated some resources that glutSetCursor() was allocating in the
X server.

(168) Added {ReparentNotify} (event type 21) case to glutMainLoop().

(169) Clear window callbacks during window destruction.

(170) Implement visible/invisible support for WIN32.  (Partial?  No
callback added at this time.)

*******************************************************************************************
* Changes on November 8, 2003
*******************************************************************************************

(171) Altered the way that {random} was chosen in the fractals_random.c
program, in order to attempt to gain a longer cycle before repeating.

(172) More style issues.

*******************************************************************************************
* Changes on November 9, 2003
*******************************************************************************************

(173) Added some error-checking to the glutSetCursor() code on my
NetBSD (UNIX_X11) system.

*******************************************************************************************
* Changes on November 10, 2003
*******************************************************************************************

(174) Reversed the Fractals_random changes; they were bogus since they
assumed that there were always exactly 4 affine transforms to choose
from (which is certainly not guaranteed!).  Back to just shifting by
10 bits and going modulo the number of transforms.

*******************************************************************************************
* Changes on November 11, 2003
*******************************************************************************************

(175) Retroactively updated the ChangeLog file for all of the commits by
myself (rkrolib; a.k.a. Richard Rauch) (at least as visible via on the
SourceForge "CVS message board"), summarzing changes for the sake of those
who lack both web-browser and CVS access.  Also fixed a numbering error in
the log where there were two "(110)" events.  (Plus added (174) from
November 10th by memory.)

(176) Style cleanup to the "one" demo.  (Removal of CRs, TABs, mostly.)

(177) Changed the "one" demo to do glutInit*() calls before glutInit(),
proper.  This allows command-line parameters to override built-in
behavior.

(178) Complete purge of all remaining TABs from freeglut's *.[ch] files.
Also verified that (as far as I can tell) all CRs are removed from all
files where they do not belong.
        
*******************************************************************************************
* Freeglut 2.2.0 RC 1 Released on  December 10, 2003!
*******************************************************************************************

(179) CallbackMaker.dsp, demos.dsw, shapes.dsp all updated and are
packaged with distributions

(180) Fix for the window sizes on Win32 (Nigel Stewart)

(182) With permission from Steve Baker, John Fay imported the latest joystick
code from PLIB into freeglut.  This is expected to provide better support
joysticks such as USB joysticks.  However, it is largely untested beyond
compiling, and likely will require some debugging.

        
***************************************************************************
* Changes on February 7, 2004.
***************************************************************************

(183) Richard Rauch added experimental support for a new feature:
GLUT_OFFSCREEN as a rendering mode (as proposed by Nigel Stewart).
The intent is that you specify GLUT_OFFSCREEN as a GLUT display mode,
and then open a "window" much as you would a regular top-level window.
Only UNIX_X11 is supprted at this point, for lack of knowledge.

*********************************
* March 8, 2004.

(184) Made the include path for "freeglut.h" global (in "<>") rather
than local (in quotes).

(186) Per demands of project owner, offscreen rendering is now removed
from freeglut.

(187) Added support for Windows CE.

(188) Fixed an array-bounds error in X11 key-repeat detection

*********************************
* May 12, 2004.
*********************************

(189) Fixed a bug in direct/indirect rendering context and generally made
it rational.

(190) Created "GLUT_XLIB_IMPLEMENTATION" defined constant

(191) Removed a false deprecation message of "glutSetKeyRepeat" function

(192) Implemented the upper-end ASCII characters and allowed for rotation
of bitmapped text.

(193) Removed some obsolete defined constants.

(194) Fixed a bug in the "behaviour on window close" code.

(195) Added some comments about Windows window events.

(196) Implemented the GLUT teapot in Windows CE.

*********************************
* June 29, 2004.
*********************************

(197) Gave menu windows the name "freeglut menu" instead of NULL

*********************************
* August 4, 2004.
*********************************

(198) Fixed a bug in "glutBitmapString" so that it handles end-of-line
characters correctly.

*********************************
* August 5, 2004.
*********************************

(199) Suppressed warnings about indirect rendering contexts for BSD per
request from Richard Rauch.

*********************************
* August 11, 2004.
*********************************

(200) Fixed a very nasty game mode bug that was causing crashes with the
screen in a changed (low) resolution.

*********************************
* September 10, 2004.
*********************************

(201) Modified the joystick initialization so that it only happens if the
application defines a joystick callback.

(202) Changed many three-line comments to single-line comments.

*********************************
* September 13, 2004.
*********************************

(203) Removed redundant end-of-line characters from error and warning
messages.

(204) Renamed "fgGetCursorError" and made it and some other functions static.

(205) Added a warning message to game mode get function.

*********************************
* September 15, 2004.
*********************************

(206) Fixed a bug in the command line argument compaction code.

*********************************
* September 23, 2004.
*********************************

(207) Changed "fgError" calls in the font routines to "fgWarning" so that
execution can continue even if text does not get printed.

(208) Made the geometry functions more robust in case the application calls
them with bad inputs (like zero layers in a cone).

(209) Unified the tetrahedron and Sierpinski sponge code.

(210) Made the Key Repeat default behaviour consistent between initialization
and reinitialization.

(211) Removed duplicate nested parentheses.

(212) Changed some "window by handle" internal functions to receive the window
pointer instead of looking up the window pointer right away.

(213) Removed some redundant window resize code.

*********************************
* October 5, 2004.
*********************************

(214) Added British spellings to the display mode string processing.

(215) Modified the mouse behaviour in Windows to match the X11 behaviour.  It's
not perfect but it is much improved.  The question of multiple button presses
at once remains.

*********************************
* October 6, 2004.
*********************************

(216) Moved the joystick initialization code to one function.

(217) Added some functions to get joystick parameters (number of buttons, axes).
It is not clear whether these should go into the API or not.

*********************************
* December 17, 2004.
*********************************

(218) Changed the "freeglut_assert_window" to "fgError" and had it print out
the name of the function whose call created the error condition.

(219) Changed the "freeglut_assert_ready" to "fgError" when it is invoked in
an API function and had it print out the name of the function whose call
created the error condition.  Removed some other "freeglut_assert_ready"
invocations from functions which are only called from other functions which
already check for initialization.

***************************************************************************
* Changes on December 31, 2004.
***************************************************************************

(220) Fixed bug #1079530 (glutGetProcAddress and geometric objects).

(221) Fixed bug #1087642 (glutDeviceGet(GLUT_DEVICE_KEY_REPEAT)
unimplemented).

(222) Fixed bug #1045054 (KeyReleaseMask typo).

(223) Fixed bug #1040435 (glutBitmapString() bug).

(224) Fixed first bug of #1064195 (two things when using signals):
Don't issue a warning about select when a non-blocked signal was
caught. This makes sense and is more compatible with GLUT.

***************************************************************************
* Changes on January 1, 2005.
***************************************************************************

(225) Added eMbedded Visual Tools project/workspace files to
distribution.

(226) Renamed "configure.in" to the officially preferred
"configure.ac".

(227) Make "gcc -Wall -pedantic -Werror" happy.

(228) Modernized configure.ac a bit and added a rule to Makefile.am to
update libtool. Note that all gcc compiler warnings are now on by
default.

(229) Added missing files from "src" subdirectory to dist.

***************************************************************************
* Changes on January 3, 2005.
***************************************************************************

(230) Removed acconfig.h, it is deprecated and we don't need it.

(231) Cleaned up and autoconf'd the header inclusion story a bit.

(232) Improved error message a bit when no suitable visual could be found
(X11 only).

(233) Fixed part of bug #926883 (Video mode matching code, memory leaks,
fullscreen), i.e. memory leak caused by not freeing the mode lines returned
by XF86VidModeGetAllModeLines

(234) Fixed part of bug #926883 (Video mode matching code, memory leaks,
fullscreen): Now we first try to get an exact mode match, ignoring the
refresh rate if none could be found. This way the X11 part and the WinDoze
behave similarly. NOTE: We still don't behave like GLUT, because it has a
wider notion of "best" match. We have to refactor and extend freeglut quite
a bit to do that.

(235) Fixed part of bug #926883 (Video mode matching code, memory leaks,
fullscreen), i.e. issue warnings when XF86VidModeFOO fails.
