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.

adds the changes to SkPreConfig.h as a patch listed in  gfx/skia/patches

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)...
