R_InitOpenGL
This function is responsible for initializing a valid OpenGL subsystem
for rendering. This is done by calling the system specific GLimp_Init,
which gives us a working OGL subsystem, then setting all necessary openGL
state, including images, vertex programs, and display lists.
Changes to the vertex cache size or smp state require a vid_restart.
If glConfig.isInitialized is false, no rendering can take place, but
all renderSystem functions will still operate properly, notably the material
