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 R_IsInitialized() is false, no rendering can take place, but

all renderSystem functions will still operate properly, notably the material
|
|
and model information functions.
