40 * TODO BEFORE THE STABLE RELEASE:
41 * glutSetCursor() -- Win32 mappings are incomplete.
43 * It would be good to use custom mouse cursor shapes, and introduce
44 * an option to display them using glBitmap() and/or texture mapping,
45 * apart from the windowing system version.

63 * (X) GLUT_CURSOR_NONE doesn't do what it should. We can probably
64 * build an empty pixmap for it, though, quite painlessly.
65 * (X) Are we allocating resources, or causing X to do so?
66 * If yes, we should arrange to deallocate!
67 * (c) No error checking. Is that a problem?
68 * (d) FULL_CROSSHAIR demotes to plain CROSSHAIR. Old GLUT allows
69 * for this, but if there is a system that easily supports a full-
70 * window (or full-screen) crosshair, we might consider it.
71 * (e) Out-of-range cursor-types are ignored. Should we abort?
72 * Print a warning message?
