cc: Fix invalidation problems in impl-side painting
The PictureLayerTiling iterator used to stop when it hit a null tile
rather than iterating through null tiles. So, some invalidations were
ignored because the iterator would hit a null tile from a previous
invalidation rect on the same frame and abort.
This is fixed by making the PictureLayerTiling iterator walk over all i,
j pairs, regardless of whether there is a tile there or not. The
PictureLayerTilingSet iteration is also made robust to this possibility.
