Description Simon Fraser (smfr) 2011-09-16 13:24:54 PDT
Images of WK2 views flatten 3d transforms (they do a flattening paint, rather than capturing the window). This breaks pixel tests that contain 3d rendering (e.g. compositing/flat-with-transformed-child.html), and means that Safari snapshots don't show 3d.

I think that if we used "svn move" I could see the changes to this file. Because we just added a new file, I can’t see the diffs.

git will end up detecting the rename and will show this as an svn mv on commit.

This causes a leak. You need to adopt the image.
