Documentation

This is the OS/2 OpenGL 2D driver. I did not had any chance to test it on any videocard that supports hardware acceleration for OS/2 OpenGL but I hope it will work.
The OS/2 OpenGL window is not resizeable as Crystal Space does not support dynamically resizeable windows. The support for color index modes (256 color) is not (yet?) functional (it's the fault of 3D driver).

UInt PixelFormat

Pixel format (a combination of GLCF_XXX)

UInt LineAddressFrameW

The width for which LineAddress has been computed last time

glWindow* glW
