Revert of Fix dst bound reported by SkTileImageFilter (patchset #3 id:40001 of https://codereview.chromium.org/1152553006/)
Reason for revert: breaking tests Original issue's description: > Fix dst bound reported by SkTileImageFilter > > In the example from the bug we had the filter DAG: > > color filter (table) > 0: xfermode filter (arith) > 0: tile filter [0,80,34,114] -> [0,80,800,480] > 0: color filter (table) > 0: bitmap src 34x34 -> [0,80,34,114] > 1: color filter (table) > 0: picture filter [0, 80, 800, 480] > > computeFastBounds was coming out of the DAG with a bound of [0,80,34,114] which didn't represent the pixels that would be drawn. > > This CL updates SkTileImageFilter to correctly set the bound for the pixels it will hit. > > BUG=493783 > > Committed: https://skia.googlesource.com/skia/+/05be93bbdf09576f7903130e3b106b0a8c7c4b4e TBR=reed@google.com,senorblanco@google.com,senorblanco@chromium.org NOPRESUBMIT=true NOTREECHECKS=true NOTRY=true BUG=493783 Review URL: https://codereview.chromium.org/1143083006
