This is a bit sloppy in that it ignores some instances where discards were being issued before. The creation of the temp RTContext in the RenderTarget's discard method was causing an extra split in the opLists. This is split out of: https://skia-review.googlesource.com/c/10284/ (Omnibus: Remove GrSurface-derived classes from ops) Change-Id: Ic366d303280635763b0fae238c4df37c04fb8503 Reviewed-on: https://skia-review.googlesource.com/11125 Commit-Queue: Robert Phillips <robertphillips@google.com> Reviewed-by: Brian Salomon <bsalomon@google.com>
