    vmwgfx: Reduce system resource usage with textured video
    
    Use U and V textures and corresponding dma buffers that match
    the size of the input UV data rather than using textures and DMA buffers
    that match the Y data. This simplifies data copy and reduces the amount of
    image data transfered to the host by up to 50% (YV12).
    
    It also reduces dma buffer- and surface memory usage correspondingly.
