While working on bug 1504590 one of the things I'm trying to do is to force a new raster root at the root of a perspective reference frame (right now this doesn't happen, see bug 1504590 comment 13). So I wrote this patch but it basically breaks perspective rendering: try push and reftest view.
Discussing with :kvark or IRC, this might be a bug. In theory it seems like forcing a stacking context to be isolated should only result in fuzz differences (snapping/AA) but in this case it affects rendering significantly.

I want to keep this on my radar a bit since it probably explains some of the weirdness I'm seeing while debugging some perspective / preserve-3d issues.
