    vmware/vmwgfx: Make large Xv video blits cheaper
    
    As screens grow larger, attempt to make large Xv video blits cheaper by
    performing the color conversion and scaling in two steps:
    
    1) Color conversion which has a 4x4 matrix multiplication shader is performed
       to a bounce buffer the size of which is never larger than the source image.
    2) Scaling is performed as a src composite blit to the destination image with
       a simple copy shader.
    
    This split is done only if the destination image is substantially larger than
    the source image / bounce buffer
