Patterns are recreated every time they paint

This is is a possible perf regression from the previous behavior where patterns
were cached based on CTM over in the Canvas2dGraphicsContext object.  Now that
they're over on GraphicsContext we don't have a similar system for caching
(yet).  This bug is about building one so that we aren't recreating patterns
every time we draw them.
