commit 5caf806d42a1909ff3a7716d8bc592fa68a02377

    sna: BLT use dword pitch only for tiled surfaces
    
    The gen4+ spec is a little misleading as states that all BLT pitches for
    the XY commands are in dwords. Apparently not, as the upload/download
    functions were already demonstrating. This only became apparent when
    accelerating core text routines to offscreen pixmaps, such as composited
    windows.
