Add support for the following drawing functions: - drawBitmap(int[]...) - drawPaint() Optimizes shader state changes by enabling/disabling attribute arrays only when needed. Adds quick rejects when drawing trivial shapes to avoid unnecessary OpenGL operations. Change-Id: Ic2c6c2ed1523d08a63a8c95601a1ec40b6c7fbc9
