I was drawing a path into a layer. Lets say I can't access that drawing code in any way, because it comes from a compiled lib. Now I want to let that layer throw a shadow which matches the shape of its irregular content shape.
Is there an easy way to do it? Or must I draw like 20 of those layers and scale them up on every iteration, adjusting their alpha and letting the GPU do the extraordinarily heavy compositing?
