+ Add layout tests to make sure a gif image is still animated if:
+ - It is used as a background image of a 0-height html element
+ - It is used as a background image of a 0-height body element that
+ is delegated to the root (because the root has no background)
+
+ Also add a layout test to make sure we still stop the gif animation
+ if it is used as background image of a body that is outside the
+ viewport.

+
+ After r163928, we would fail to animate a gif if:
+ - it is used as a background image of a 0-height html element
+ - it is used as a background image of a 0-height body element whose
+ background is delegated to the root (because the root has no
+ background).
+
+ This is because in such cases, shouldRepaintForImageAnimation()
+ should use the background rect instead of the renderer's overflow
+ rect to determine if the image is inside the viewport. Both cases
+ are addressed in this patch.
