Tweak SkPictureShader's tile semantics.
Currently, the tile offset is added when drawing the picture. This might
have made a tiny bit of sense when the picture was always positioned at
origin, but with a picture cull rect offset things looks really strange.
For example, to specify a tile == the picture cull rect we have to pass
in [-cullrect.x, -cullrect.y, cullrect.width, cullrect.height]. Yikes.
(there's also a bug when not passing a tile, as we use a default tile
== cullrect but don't compensate for the above oddity)
This changes the semantics of the tile offset: it is now subtracted when
drawing the picture tile. As a consequence, one can pass in a tile equal
to the cull rect and get the expected behavior (same when not passing
a tile).
This will require a minor Blink change with the roll, as one client
works around the current behavior:
