I am not sure if would be less efficient. If I figure out the way CALayer works correctly, at the OpenGL level, your path has to be rasterized, filled then put into some kind of auxiliary buffer (stencil); Afterwards the OpenGL fragment processor clips the rendering according to the values of the corresponding pixel in the stencil buffer. If you pass a clip mask, that goes directly into the auxiliary buffer. Is there any pundit out here to confirm this?
