Ambient shadow tessellation improvement.
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.

Tessellate on worker threads
Tessellate and cache (where possible) shadow and round rect
tessellation tasks.

Create one hole inside the umbra area to avoid overdraw.

Use pre-computed index to draw the shadow.
Also draw the umbra part as triangle fans instead of zig zag fashion.

Calculate and show Ambient shadow.
Basically we compute the shadow as a strip of triangles, whose alpha value
is the strength of the shadow.
We use the normal to extend the geometry.
And we use static function and try to avoid new/malloc in the computation.
