Attached patch additional fixesSplinter Review
Additional fixes on top of the backout, as requested in bug 723669.
Is this something we think we can reinstate later, or is there some fundamental issue with it?

additional fixes

Review of attachment 594602 [details] [diff] [review]:

Should we remove nsChangeHint_UpdateTransformLayer and nsChangeHint_UpdateOpacityLayer too? I think we should! It seems to me they currently have the same bug.
Please file a new bug.  This bug is only for making UpdateOverflow work for
transforms and nothing else.  The aim is to merge this to Aurora and leave it
at that state for Fx12.  Then re-land bug 719177 with some additional fixes
(as discussed in bug 723669) on trunk, except for 'text-shadow' which we can
handle in bug 723669 (if we decide to do it).
The Try run was green.  I installed the Try build on my Nexus and it seems to work
fine on sites mentioned in bug 722325, but I'm not exactly sure what to look for.

Chris, I'd appreciate if you can verify that.
Feel free to review this patch, or the backout commands + additional fixes
patch, whichever you think is easier to review.

Sure, filed bug 724502. I'll try to fix it.
Attachment #594799 - Flags: review?(roc)
This caused bug 722325 to regress again, so I re-instated that wallpaper and
filed bug 725664 to fix it for real.  The question is - what do we want to do
for Aurora?  Ship with the wallpaper or revert UpdateOverflow also for transforms?
Attached file backout for Aurora
Ok, here's the backout commands for Aurora.  Specifically, I'm NOT backing out
the wallpaper for bug 722325, which landed independently for Aurora in

On top of that, the same "additional fixes" patch.
These changes will make the affected code the same as currently on trunk.
