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. issue #4713
