There were a few missing methods that should have been reimplmented
(because they were native).
Others have been added just to be sure so that we can test whether methods
are missing or not (test coming soon).

- Make the custom Canvas actually replace the original one so that it's used
even by parts of the framework that allocate their own temp Canvas object.
- Better support for Matrix: added support for mapPoint() and mapRect(), and invert()
- Implemented drawBitmap() with a Matrix, and made the paint object not NPE when null.
