This looks questionable, we use the FVF to determine that the buffer
is going to need conversion, but don't pass that FVF to the buffer
itself? Shouldn't this just use the existing code in buffer.c to
determine when we need conversion in the first place, and just drop
the VBO when the overhead becomes too large? Note that if we have
EXT_vertex_array_bgra we don't need conversion for the color data in
the first place.
