test case

Don't know if this is a duplicate of the various gradients bugs out there, but in the hope that this is useful and not yet reported, here's a sample file with a gradient on page 3 (the thermometer). It renders differently in Evince than in Acroread.

After comparing several this pdf on several renderers, and noting that mupdf also got it wrong — though in a different way than poppler does — I posted about it on gs’ bz.

Tor checked it and replied:

Tor> It’s an image not a linear gradient. I suspect it’s the same bug as 690666
Tor> where [mupdf’s] interpolation on the edges of images is wrong.

Yes, this is indeed already fixed in git master. Thanks!
