/*
21
TGLFormat class describes the pixel format of a drawing surface.
22
It's a generic analog of PIXELFORMATDESCRIPTOR (win32) or
23
array of integer constants array for glXChooseVisual (X11).
24
This class is in a very preliminary state, different
25
options have not been tested yet, only defaults.
26
27
Surface can be:
28
-RGBA
29
-with/without depth buffer
30
-with/without stencil buffer
31
-with/without accum buffer
32
-double/single buffered
