Gradients have visible discrepancies across clip boundaries
Project Member Reported by firstname.lastname@example.org, Aug 29 2014
Run ToT Chromium and open third_party/WebKit/fast/hidpi/gradient-with-scaled-ancestor.html. Run Chrome with --enable-impl-side-painting and then again with --disable-impl-side-painting and compare. There's a very obvious visual discrepancy in the gradient when impl-side painting is enabled. This seems like a "playback with SkPicture and clip" vs "raster into SkCanvas directly" sort of bug.
