Bug 486918 added new image resizers from SKIA.  Since this was enabled
resized images on my ppc32 machine show up with a blue tint.

The convolver code extracts the RGBA bits from each 32 bit pixel but
doesn't take the endian order into account.

proposed fix.  Detect that this is a PPC and set the BENDIAN then use that when

Can you just leave these all on the same line?

I would strongly recommend that the change to SkPreConfig.h gets a patch
file added to gfx/skia/patches, or that this change be upstreamed to
google's skia repo (or both!).

Otherwise this change is at risk of being overwritten when we next
update skia.

This patch will add a patch file in gfx/skia/patches to alter
SkPreConfig.h the next time we import upstream sources

Sorry! I was confusing SkPreConfig.h with SkUserConfig.h, and
incorrectly figured it didn't need to have a separate patch.

Apparently attachment #690255 never went through review in m-c nor
commited, and neither upstream who didnt reply on codereview. Should it
be unbitrotten and r?'ed ?

Stumbled upon this while investigating why skia got broken on ppc again
(see #849253)...

Title:
  Some images have a blue tint

Status in The Mozilla Firefox Browser:
  Fix Released
Status in “firefox” package in Ubuntu:
  Fix Released

Bug description:
  Firefox 19.0 on Xubuntu 12.10 on a Late 2005 Apple Mac mini.

  Steps to reproduce:

  1. Open Firefox.
  2. Navigate to an image-heavy website (Flickr, for instance). Note that some 
images have a blue tint.
  3. If you already have enough of a browsing history, open a new tab and 
observe that the screenshots of your most visited pages also look too blue.

  Downgrading back to version 18.2 makes the problem go away, although
  using an outdated browser is not much of a workaround.

  I can test if required.
