OpenGL render support in SDL render
|Reported by:||SF/luke_br||Owned by:|
Adds OpenGL render support in the new sdl.cpp (from 4th of May, 2002). Advantages: bilinear filtering in fullscreen mode without loss of speed with 3d OpenGL accelerators.
It needs the fb2opengl.h routines (it's being sent too).
