Details
The just-added pngsuite-background reftests fail on Linux. The test looks ok at first glance, but a quick look at one pixel shows it off by 1. These images are all partial transparency over a solid color background. I suspect it's just a case of the alpha blending having slight platform differences. For now, I'm marking the test as only passing on OS X. [Windows was already expected to fail, due to bug 405384]

Are you using the embedded libpng or the system libpng? Do you have gfx.color_management.enabled enabled? What happens if you change the gfx.color_management.enabled setting and restart your browser? Note that although the pngsuite-background test series has PNG bKGD chunks, that is of no conseqence to mozilla because we always ignore the bKGD chunk. The files also all have an alpha channel and a gamma=1.0 chunk.
