* initClassID no longer auto-allocates idsGravatar Ethan Nicholas2017-10-09
| | | | | | | | | | | | | Auto-allocated IDs mean that the IDs depend upon the order in which classes happen to get initialized and are therefore not consistent from run to run. This change paves the way for a persistent shader cache by fixing the IDs in an enum.

* 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.

* Start of rewrite of GrFragmentProcessor optimizations.Gravatar Brian Salomon2017-01-27
| | | | | | | | | | | | | | | | | This adds a replacement for computeInvariantOutput buts does not use it yet. The replacement allows for three types of optimizations: * known input color -> known output color for GrFP elimination * tracking of whether all color processors modulate their input for the "tweak alpha" optimziation * opaqueness tracking This loses some of the generality of computInvariantOutput. It does not track the known output status of individual color components (other than opaque alpha). It does not track whether GrFragmentProcessors read their input color. It doesn't allow a processor that will receive non-constant output to advertise that it produces a constant output. These could probably be added back in the unlikely case that they prove valuable. Unlike computeInvariantOutput the optimizations are decided at instantiation time and constant colors are expressed as GrColor4f rather than GrColor.
