From 1db141f93c4fe79a4669440c3d14f63bc87b2e34 Mon Sep 17 00:00:00 2001 From: Derek Sollenberger Date: Tue, 16 Dec 2014 08:37:20 -0500 Subject: Create proxy between Skia's SkCanvas and the framework Canvas. This enables Picture.java to be replayed into HWUI in addition to extending the Skia testing suite to HWUI.
