From 0b7e8245db728d127ada698be63d78b33fc6e4da Mon Sep 17 00:00:00 2001 From: Chris Craik Date: Wed, 28 Oct 2015 16:50:44 -0700 Subject: Initial HW layer support in new reorderer/renderer Shares vast majority of clipped savelayer code, with only minor differences in lifecycle. Doesn't yet handle fill region, resize, or window transform.
