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
