38 * TODO BEFORE THE STABLE RELEASE:
40 * fgChooseVisual() -- OK, but what about glutInitDisplayString()?
41 * fgSetupPixelFormat -- ignores the display mode settings
42 * fgOpenWindow() -- check the Win32 version, -iconic handling!
43 * fgCloseWindow() -- check the Win32 version
44 * glutCreateWindow() -- see what happens when default position and size is {-1,-1}
45 * glutCreateSubWindow() -- see what happens when default position and size is {-1,-1}
46 * glutDestroyWindow() -- check the Win32 version
47 * glutSetWindow() -- check the Win32 version
48 * glutGetWindow() -- OK
49 * glutSetWindowTitle() -- check the Win32 version
50 * glutSetIconTitle() -- check the Win32 version
51 * glutShowWindow() -- check the Win32 version
52 * glutHideWindow() -- check the Win32 version
53 * glutIconifyWindow() -- check the Win32 version
54 * glutReshapeWindow() -- check the Win32 version
55 * glutPositionWindow() -- check the Win32 version
56 * glutPushWindow() -- check the Win32 version
