Implement bounds traversals for tile and matrix convolution filters.
Add a new GM that exercises tiled drawing all pixel-moving filters
(and some non-pixel-moving ones) and compares it against non-tiled
drawing of the same filters. Fixing this test revealed that tile and
matrix convolution filters had no onFilterBounds() traversals
(test-driven development FTW). Tile requires (conservatively) the
bounds to include the whole source rect, since it may end up in the
result. Matrix convolution requires the bounds to be offset by the
kernel size and target.
