From 2b3bf720bf28584f700ad8ebb5e8e31a0e466f29 Mon Sep 17 00:00:00 2001 From: Robert Carr Date: Thu, 7 Jan 2016 17:50:48 -0800 Subject: Implement surfaceRedrawNeeded for GLSurfaceView GLSurfaceView was not supporting the surfaceRedrawNeeded protocol which leads to issues with report draw. Thus far this has mostly been fine as the main surface will not render a transparent hole until the SurfaceView has finished drawing. However in the case of SurfaceView replacement the hole in the parent surface will be preexisting and we must be able to tell that our new SurfaceView has actually drawn before removing the replacee. This is part of a series of fixes to 26070641.
