* Refactor GaussianBlurGravatar Robert Phillips2018-04-25
| | | | | | | | | | | | | One of the bounding boxes in this method goes haywire in DDL mode. Hopefully, this refactoring will make it easier to determine which one it is. Note that in this CL I tried to not change the existing behavior at all.

* Added new edge handling mode (clamp and repeat) to Gaussian blur filter.Gravatar wutao2017-06-30
| | | | | | | | | | | | | | | | | | | Gaussian blur filter will interpolate value by using out of bounds coords, which is 0. This makes it appears darker near the bounds in the blurred images. There are two issues: 1) when downsampling and upsampling, we should use GrTextureDomainEffect kClamp_Mode to clamp the texture coords to the bounds; 2) during Gaussian blur, we need to clamp to texture bounds.

* Add GM image test for blur with clamp mode.Gravatar wutao2017-06-27
Adding a GM (Golden Master) image test in Skia to reproduce the bleed black issue in Chrome. This would allow regressions to be caught in Skia's status page before being rolled into Chrome.
