    mesa: Implement a new GL_MESA_tile_raster_order extension. · e6764348
    Eric Anholt authored
    The intent is to use this extension on vc4 to allow X11 to do overlapping
    CopyArea() within a pixmap without first blitting the pixmap to a
    temporary.  With associated glamor patches, improves x11perf
    -copywinwin100 performance on a Raspberry Pi 3 from ~4700/sec to
    ~5130/sec, and is an even larger boost to uncomposited window movement
    performance (most copywinwin100 copies don't overlap).
    
    v2: Fix glIsEnabled() on the new enums.
    v3: Drop the local spec since I'm upstreaming the spec.
