From 45580d3e3024c1536e8e1b2017b704805442b634 Mon Sep 17 00:00:00 2001 From: Brian Osman Date: Wed, 23 Nov 2016 09:37:01 -0500 Subject: Added GrSurfaceContext and GrTextureContext This lets copy-to-texture to be treated like copy-to-rt. To match current behavior, though, copies to texture are still executed immediately (forcing a flush). Once MDB is enabled, copies to texture will be deferred.
