This better matches Chrome's use of DDLs.
With path, image, and text draws stripped out, here is the perf impact of this change:
before CL after CL
w/ DDLs 7.792 1.038
w/o DDLs 0.800 0.876
This perf improvement (in the DDL case) is from backend texture wrapping SkSurfaces being created w/o initialization. The prior method of SkSurface creation was resulting in double clearing of all the surfaces.
This perf improvement won't be seen by Chrome since they've always being using wrapped backend texture SkSurfaces.
