Summary [Cairo] Improve ShadowBlur performance using tiling optimization
Tomoki Imai
Reported 2019-04-25 23:20:23 PDT
We want to enable tiling tiling-based optimization for drawRectShadow() and drawInsetShadow(). Since r228776, cairo ports doesn't have tiling-based optimization, we see some performance regressions.

I ran LayoutTests for WinCairo and GTK, and didn't see any regression cases.
