------- Additional Comments from Dana Jansens <danakj at chromium.org>
Put the blending decision behind a single public function: bool
drawWithBlending().

Made protected methods to decide blending based on the contents of the layer
(i.e. are all pixels opaque), and the edges of the layer (i.e. is it
rectilinear or does it require anti-aliasing for the edges).
