[cairo] [PATCH 0/2] Update pixman reference images

[Bryce Harrington]

The downscaling tests check all the different filter levels, to three
different scales.  Two of the scales, 96:96 and 96:24, are easy scaling
settings and thus should produce essentially identical results.  The
third scaling, 96:95, requires blurring the lines bordering solid
colors, and we generally are fairly permissive as to what the renderer
decides to do.  Unfortunately the various backends seem to vary quite a
bit in what they choose to do.

Because of this, I'm tempted to just drop the 96:95 scale test since it
will always be finicky.  However, I do think it's important that we test
"off" scales like this.

But meantime, here are updates of the reference images, along with a
update-refs.sh script I used to copy the refs from the test output.
This works to avoid adding redundant reference images by testing them
before copying them.  This script may be worth extending if we have
other tests that need their reference images updated to match test
output.
