Two questions regarding KWinEffect API

Hi KWin team.

I am developing a KWin effect and I have two questions:
1. How can I paint the shadow of the window only? I am trying to make some
changes in the decoration and I wished there was a separation between
painting the shadow and painting the window.
2. How can I apply my effect before the Wobbly effect gets applied? It
looks like the order of effects that are rendering matters in my
development.
