This directory contains reference images for graphics_GLBench test.  After
uncompressing to RGBA these images will match checksums in
glbench/src/checksums.  For example:

    > convert mpixels_sec_clear_color.png rgba:- | md5sum
    e3609de1022a164fe240a562c69367de

"convert" tool comes from imagemagick package.

graphics_GLBench dumps raw RGBA images if -save flag is specified.  To convert
a raw image from the test back to png for storing here, "convert" utility can
be used like this:

    convert -size 512x512 -depth 8 rgba:mpixels_sec_clear_color \
        mpixels_sec_clear_color.png
