Correctly rebuild cc::PaintCanvas matrix stack when layers are used.

Whenever a frame is rendered while layers are opened (e.g. by calling
getImageData between calls to beginLayer and endLayer), the
cc::PaintCanvas stack have to be flushed and all layer closed. This stack
then has to be rebuilt, re-opening any layers that were previously
opened.
