Oxygen::ShadowCache::shadowSize() now returns the shadow extend outside of the window body (the extend) Overlab between the actual shadow pixmap and the window body is dealt with internally (by creating larger pixmaps) This allows notably Oxygen::Client to not attempt to draw shadow when shadowSize == 0 (which was never the case before)
