42 * TODO BEFORE THE STABLE RELEASE:
44 * fgDisplayCursor() -- this waits for better times
45 * glutSetCursor() -- both X and Win32 mappings are incomplete
47 * It would be good to use custom mouse cursor shapes, and introduce
48 * an option to display them using glBitmap() and/or texture mapping,
49 * apart from the windowing system version.

80 * (a) GLUT_CURSOR_NONE doesn't do what it should.
81 * (b) Are we allocating resources, or causing X to do so?
82 * If yes, we should arrange to deallocate!
83 * (c) No error checking. Is that a problem?
89 * For now we'll limit ourselves to the X cursor fonts...
