From 200f783745b571725f899f08c34d1155be632523 Mon Sep 17 00:00:00 2001 From: Charles Yin Date: Wed, 28 Mar 2012 00:06:28 +1000 Subject: [PATCH] Fix context2d transform issues After calling transform related methods, the current path should be transformed with the same method but in reversal mode. So that during painting, the painter will apply the CTM to this path again, otherwise path will be transformed twice.
