Use the dest_rect parameter to subset in OptimizeToSingleTileDraw()

When painting boxes with rounded corners, the provided dest_rect can
differ slightly from the one(s) in BackgroundImageGeometry. Since the
former is what defines the actual drawing operation, using the latter
can lead to a distorted image.

Use the parameter rectangle when sub-setting to get the subset that
matches the intended draw.

Affects rendering of some generated background images (gradients)
because they will now miss the fast-path (snapped tile size vs.
unsnapped destination rectangle).
