This is a rollup of the following patches part 0: Add a dynamic cast to ColorLayer* part 1: Add a Composer2D interface to enable implementations to more efficiently compose layer trees part 2: Let widgets expose Composer2Ds, if they have them part 3: Expose a layers ogl "friend" API that Composer2D will consume part 4: Hook Composer2D into the LayerManagerOGL rendering pipeline part 5: Implement all the goop to let widget/gonk use a Composer2D (HwcComposer2D)
