Michael Fabian 'Xaymar' Dirks ccc4c6ea22 filter-sdf-effects: Fix and improve effect rendering 
Fixes the bug that rendering an outline would remove all other effects not directly under the outline, while also improving the rendering speed drastically by only initializing and clearing the rendertarget once instead of for each effect.
