Modified the menus to refer to {border} rather than {FREEGLUT_MENU_BORDER},
in fghDisplayMenuBox(). The local variable was already defined and used
for some purposes, so we might as well use it throughout. It does serve
to shorten and clarify the code a bit---though I have mixed feelings about
creating aliases that way.
Still, the variable already existed and was already used in places. (We
could even move it into the freeglut state, or make it a {const static}
value...)

Altered the way that the {random} value (from 0..3) is chosen.
Previously, it picked out two adjacent bits in the result of rand().
Unfortunately, these adjacent bits (at least on NetBSD) have a certain
amount of dependance. After a period (perhaps a thousand or so?), it
starts to repeat the pattern of those two bits. (I think; I haven't
actually tested that directly.) This presumably is locking it into a
an an N-way attractor on the "snowflake", such that if you zoom in a
ways, you will start to see some spots *quickly* are colored, and
others are *never* colored.
What I've done now is to pick up two widely-spaced bits in a single
rand() call. (Perhaps we would do as well to pick up something like
bit #16 from two consecutive rand() calls?) These widely-spaced bits
have a lower statistical dependance on one another (if I can get away
with using that term for an arithmetic operation; though since stats
has more to do with sampling and less to do with true randomness, I
may be safe).
The net effect, at leats on NetBSD, is far better snowflake if you zoom
in on it.

Slight style improvements. Two rules of thumb that are almost always
good to apply:
* Don't write a == CONST. Instead, write CONST == a. Or, more generally
(in C like languages): Avoid putting an lvalue on the left-hand side of
an == comparison. (For consistancy, I try to avoid lvalues on the left-
hand side of any comparison---but == is the most notorious.)
(An "lvalue" is a value that can safely go on the left side of an
"=" assignment, of course. (^&)
* Do not write
if( !condition )
return;
other_thing;
return;
(See page 18 of K&P's _The Elements of Programming Style_.)
Instead, it is better to just write:
if( condition )
other_thing;
return;
There are times when sacrificing structured programming (e.g., via
multiple return statements) is okay. But, here, there is no apparent
gain---indeed, there seems only loss---in the non-structured code.

Converted the "Callbacks" structure (with named members holding individual
callback pointers) to a "CallBacks" array in fgState. (This is to allow
us to write a loop to clear all callbacks from windows when the window is
dead/dying. Using this, we can safely assign NULL to each in a loop.)
Support includes two new macros, FETCH_WCB() and INVOKE_WCB(). See
freeglut_internal.h for more details there.
Some typedefs of function pointer types were altered to make them more
uniform (necessary for the macros).
All references to window-based callbacks in freeglut are updated to
use the new macros.
Old usages will cause compile-time errors.
As a side bonus, the new invocation macro sets the current window and
checks pointers so that these common steps can be uniformly done on
every window-based callback. This makes it easier to do things right.
At the same time, the array notation (and now required associated casts)
make it harder to bypass the macros and abuse the function pointers,
in general.
After this commit, I will go through the code and clean up dangling issues
about formatting. This commit is just a "it now works, let's checkpoint it"

* Fixed a bug in the X11 handling of scrollwheel/mouse. The old code,
I believe, checked if *either* a wheel or button callback was set,
and then decided which to use---and unconditionally called it.
I left the "either" check in, but added additional checks before
actually doing the invocation.
* Lots of reformatting. Massive. The usual suspects, though, and fairly

the freeglut "standard" of:

Grrr. My attempt to commit got aborted, and the commit message was lost.
Now I've lost track of what I said I'd done. Something like:
* Fixed some issues with multiple wheels.
* Noted in comments some issues about other-than-3-real-buttons.
* Fixed formatting to fit 80 columns.
* Removed some BCPL/C++ style comments (//) that are not legal, and
which, if memory servers, are not even strictly legal when disabled
by preprocessor directives. E.g.,
#if 0
not-syntactically-valid-C
#endif
...is not legal. Though most cpp's will discard the bracketed material
completely before the main C compiler pass has a chance to analyze the
syntax. (MSVC++ and GCC both don't seem to mind the BCPL style comments
in plain C, but let's keep the sources clean, eh?)
* Fixed a problem that would have caused freeglut to report doubled
wheel events under XFree86.
Not tested other than compiling. Personally, I think that the interface
is inherently broken at this point unless you are willing to get user-
configuration. (Which would then solve the complaint that Steve had
about computing the tick-size on behalf of applications.) I.e., there
is NO WAY to know if we have the right buttons to start wheels at, or
if there are any buttons after the first wheel(s), etc. We just have to
guess---and if we are wrong, we can get varying degrees of brokeness.

Minor modifications to the menus:
* Updated an old "TODO BEFORE STABLE" comment.
* Expanded a comment re. some #define macros.
* Made colors and font choice system dependant. The UNIX freeglut
menus look more like UNIX GLUT menus, now. (This is PURELY a
cosmetic change. But it achieves better compatibility visually.)

* Deleted numerous say-nothing-new comments.
* Reformatted a say-something-useful comment to fit on an 80-column

Partially (re-?)unified some of the glutMainLoopEvent() code. The only
code that really needs to be system-specific is the window event handling,
which in MS-WINDOWS is tucked into a separate function. In UNIX/X11, it's
all spilled out into glutMainLoopEvent() for some reason.
If the X11 code could be tucked into another function, glutMainLoopEvent()
could be platform-independant.

Moved the idle callback out of glutMainLoopEvent() and into
glutMainLoop(), per discussion on the list. The code looks okay,
to me, though I remain less than wholly convinced that treating idles
as special cases is the best way to go. Still, a case can be made
for taking "non-event" idle callbacks out of the "event loop".
From an organizational perspective, I think that it's an improvement,
and it fixes a bug for at least one program.

Added John's text-positioning modification.
The lines that he was altering were very oddly-split, so while I was at
it, I repaired the line-break damage.

Committed change from Nigel to fix the joystick bug. (The joystick
code was not setting the GLUT window prior to calling callbacks.)
Please verify. If so, this closes out, I think, the latter half of
that bug report, so anyone with the means to modify/close bug reports
should do so upon verification of the fix.

Superficial cleanup of the code. Mostly taking lines such as:
...
/*
* <Enslish recapituation of the single following C statement>
*/
<single C statement>
...and rewrote as:

<single C statement>
freeglut_main.c still has a lot of that in it, but it looks a bit
better, now.

Added some error-checking (particularly w.r.t. strdup()).
Deleted numerous 4-line "padding" sequences of C-as-English trans-
literation comments.
Re-indented some (but not all) code that is using 2-space indentation.
(Most of the freeglut code seems to be using 4-space indentation.)
I did not touch the "INIT DISPLAY STRING PARSING" code, since it is
filled with a ton of over-long lines and also appears to be in more
flux than the rest of the code. (Well, I added one error-check
to a strdup().)

Swept the freeglut_font.c for comment cleanup:
* Got rid of the "rewrite C as English" comments.
* Corrected several bogus references to "carriage returns" (in strings).
The symbols were newlines or EOLs or LFs (\n).
They were *not* carriage returns or CRs (\r).

Small bug-fix that's been on my mind:
Modified the two Fractals* demos so that they only clear (for the random
one) or redraw (for the non-random one) if there is need to do so. (E.g.,
pressing the space bar should not clear and redraw the random fractal since
no parameters are altered.)
