1. This improve the looking, the star shape (spike) on long action bar is gone.
Shadow is more smooth now.
2. The performance is better, too. For averaging around rect, round rect and
circle, the spot shadow itself is 3 times faster. On N7 v1, it could be less than
0.1 ms.

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.

Separate matrix passed to shadow system into two parts, one for
transforming the polygon XY points (using the actual draw matrix) and
a separate one which respects correct 4x4 3d rotations and
translations for determining Z values.

True 3d transformations are now supported by DisplayLists and the
renderer, initially with the translationZ property on view.
Renderer operations used directly by DisplayList (formerly,
clip/save/restore/saveLayer) are now more simply managed by allocating
them temporarily on the handler's allocator, which exists for a single
frame. This is much simpler than continuing to expand the pool of
pre-allocated DisplayListOps now that more operations are called
directly by DisplayList, especially with z ordered drawing.
Still TODO:
-APIs for camera positioning, shadows
-Make Z apis public, and expose through XML
-Make invalidation / input 3d aware
