This reverts commit7d6fe0b996
. Reason for revert: Relanding with fix Original change's description: > Revert "Go back to using dual source blending for lcd src-over even with non-opaque color" > > This reverts commitb54bdef86e
. > > Reason for revert: breaking some bots > Original change's description: > > Go back to using dual source blending for lcd src-over even with non-opaque color > > > > This is change is currently still safe since earlier in Skia we are still requiring > > the dst to be opaque. The change is a workaround to spots where trying to read the > > dst to do in shader blending is failing for some reason. This also should give back > > a little performance since doing dual source blending should be better than shader > > blends. > > > > Bug: chromium:732341 > > Change-Id: I795f8a520f87f3fbf5d63a9509fbd9f394ea2b29 > > Reviewed-on: https://skia-review.googlesource.com/19703 > > Reviewed-by: Brian Salomon <bsalomon@google.com> > > Commit-Queue: Greg Daniel <egdaniel@google.com> > > TBR=egdaniel@google.com,bsalomon@google.com > > Change-Id: Ibb9bc1ef4ec5967dabcd62c81f62c0989c14fbb8 > No-Presubmit: true > No-Tree-Checks: true > No-Try: true > Bug: chromium:732341 > Reviewed-on: https://skia-review.googlesource.com/19815 > Reviewed-by: Greg Daniel <egdaniel@google.com> > Commit-Queue: Greg Daniel <egdaniel@google.com> TBR=egdaniel@google.com,bsalomon@google.com Bug: chromium:732341 Change-Id: I7481755a9aa64364371d8149af4458fc2c15c8aa Reviewed-on: https://skia-review.googlesource.com/19840 Reviewed-by: Brian Salomon <bsalomon@google.com> Commit-Queue: Greg Daniel <egdaniel@google.com>
