From 8514b92bc4dfab58aa762d75322e4c285b6ada17 Mon Sep 17 00:00:00 2001 From: Mathias Agopian Date: Tue, 10 Aug 2010 20:42:20 -0700 Subject: don't handle the transparent region of a layer in draw() this is already taken into consideration in computeVisibleRegion and therefore not needed at draw time.
