Updated OPENGL/SDL rendering routines
|Reported by:||SF/luke_br||Owned by:||Kirben|
Here goes the updated version of the OpenGL rendering routines (from CVS 06/09/2002). The Makefile.diff adds the option to add the needed libraries and defines for the OpenGL mode. If you comment this in the Makefile, then you will compile the normal SDL (or X11) mode. If not commented, this will generate a binary executable that *only* renders in OpenGL textures with bilinear filtering (good for people with 3d accelerators). The OpenGL routines are used in the fb2opengl.h file.
