Subject: [PATCH] Enable stencil clipping within clearLayerRegions

Previously stencil clipping within clearLayerRegions is disabled by commit
62d307c2402777d5e53b4590af5f32f8c55afd81. However, clearing whole layer
regions causes black-colored triangle regions when a TextView has
RotateAnimation because the draw within clearLayerRegions does not
affected by the current stencil clip.
