cc: RenderSurfaceImpl tile mask layer.
This is the core change of mask tiling.
In this CL, we use PictureLayerImpl::AppendQuads logic to generate Tiled
Quads out of mask layer, and convert them into RPDQs.
This change involves several space conversions and can be confusing. But
we tried our best to clarify spaces by naming them correctly.
This CL depends on the renderer change and should be commited after that.
