Fix Facebook sidebar.

Relanding http://codereview.chromium.org/20386 (r9836), this time 
with re-baselined layout tests. The change affects the pixel diffs for 
any test with a tiled css background image.

BUG = 5564
TBR= brettw
TEST= layout tests, conveniently re-baselined to pass with this change :)
