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. b/16712006 b/14257173 Change-Id: I2f22a8fe19bc59acee5c18e4a3a395acd5042a66
