Hi WG.

I have ACTION-2953 to investigate the reference images display
differently on Mac.  I suspect it is the well-known issue of Macs using
different gamma correction:

Chris, would there be anything wrong with using pngcrush to remove the
gAMA and sRGB chunks from the reference PNGs?  I verified that this
makes the SVG and reference PNGs render with the same colours on Mac and
Windows.
