    xv: workaround corruption
    
    Keeping the video pixmaps persistent sometimes will lead to video
    corruption (shifted chroma planes) for unknown reasons. Possibly
    there are some subtle pixmap handling bugs in xv or other parts of
    the glamor code. To workaround, simply destroy pixmaps after they
    have been used once.

    glamor: Fix typo in setting v_position's attrib location.
    
    Assuming it was the first attribute assigned by the GL, it would have
    ended up with location 0 anyway.

    glamor: don't reset the GLSL program
    
    We don't use fixed function rendering, so there is no need to reset
    the program at all.  This lets the driver avoid checking for state
    changes between draw calls when we rebind the same program.
    
    Improves xephyr x11perf -f8text performance by 6.03062% +/- 1.64928%

    glamor: Use glsl "fract/mod" instead of "while" in gradient shaders.
    
    This fixes gtkperf. It seemed to hang forever.

commit ecf6ce02d673780583efc338b6501c15fae18169

    glamor: Fix accelerated rendering of GTK's ARGB vs xBGR composites.
    
    There is some complicated code to support tweaking the format as we
    upload from a SHM pixmap (aka the GTK icon cache), but if we weren't
    sourcing from a SHM pixmap we just forgot to check that the formats
    matched at all.
    
    We could potentially be a little more discerning here (xRGB source and
    ARGB mask would be fine, for example), but this will all change with
    texture views anyway, so just get the rendering working for 1.16
    release.
    
    Fixes the new rendercheck gtk_argb_xbgr test.
    
    v2: Squash in keithp's fix for checking that we have a non-NULL
        pixmap, and reword the comment even more.

    vbo: Raise VBO size
    
    This reduces CPU overhead due to buffer orphaning, which results in
    a small overall performance improvement.

    glamor: Use buffer_storage
    
    29.5361% +/- 2.74092% improvement in x11perf -aa10text (n=489).
    
    Pulled from Eric's xserver glamor tree.
    
    v2: Fix fallback, return correct buffer offset, map whole buffer,
    unmap conditionally.
    v3: add conditional defines to make it compile with outdated headers.
