Using the vertices, instead of ray casting for the triangulation.
This request a dynamic index buffer associated with vertex buffer,
so we update the VertexBuffer to support it.
The ambient shadow could be 3x-6x times faster for circle and rect now.

Ensure that onStart is called prior to onCancel/onFinished if those
happen prior to the UI-thread handled start delay.
Ensure that onFinished is called if cancel/end is called

Prevent drawing transformations on a ViewGroup's canvas from directly
affecting the transformation of the children through the renderer,
since it's already baked into mTransformFromParent at record time.

This means rendernodes with a Z will no longer be drawn at the end of
their parent's DisplayList, but at the end of the associated reorder
region (DisplayListData::Chunk).

Get rid of compuation of the intersection for penumbra and convex hull for umbra.
Use simple circle / normal to compute the penumbra and simple intersection for umbra.
The new way could be 2x to 4x faster from rectangle to round shape.
And this part is roughly half of the shadow computation, or 2/3 of spot shadow
computation.
This improve the spot shadow spikeness too.

Also fixes stroked text bounds calculation.

Savelayers and HW layers both now support shadow casting.
For save layers, the light source should always be correct, for HW
layers, the light source position is set when the layer is created,
and updated when it is resized.

Use pow(alpha, 1.5) to avoid harsh edges on shadow alpha ramps.
Also adjusts shadow constants to compensate.

1) Fix projectionReceiveIndex, which could in some cases point at
translate/restore ops.
2) Use background translateX / translateY for projected RenderNodes.
This makes them match background position, and thus properly account
for scroll.

SkPath objects owned by DisplayListOps weren't being torn down, and
thus weren't releasing their SkPathRef innards.

This allows us to deduplicate a lot between the two ops, and fixes the
shader coordinate space for the left,top argument drawBitmap to match
software.
