0f15d7373bf1c2a357422d6ca5adfee10e50e880 optimize verts
Take advantage of the new virtual on SkShaderBase : appendStagesWithUpdater
If our shader supports that, we can draw each triangle without having to
recreate the entire pipeline/blitter.
This change produces 3 different loops:
tricolor only : uses private backdoor to update colors per triangle
has updater : uses updater to update ctm per triangle
general : rebuilds pipeline/blitter on each triangle
In a follow-up, we may be able to plumb updater through to other shaders
(other than image), which would have us land in the updater case more
often.
