Sebastian Sumpf 3260c86d15 gpu_session: VRAM interface
Change the abstraction from buffers to video RAM (VRAM). The notion of
buffers can be provided at the client side (e.g., Mesa) and multiple
buffers can be there be associated to one VRAM area, thus saving
resources (meta data overhead) when allocating many buffers. A VRAM area
can also be mapped to one single buffer as before for clients or drivers
that do not take advantage of this feature.
