* Add support for transfer functions to GrColorSpaceXformGravatar Brian Osman2017-10-31
| | | | | | | | | | | | | | | | | | | With this change, untagged sources (eg N32) are treated as sRGB data, which causes a huge number of GMs to render more correctly in GPU sRGB/F16/etc... configs. Also, because the sources are treated as having a color space, we actually do gamut conversion for wide or narrow gamut outputs. This change also applies the transfer function math to individual colors in the case of gradient stops and color shaders. (The CPU backend doesn't do this yet, but I think we've decided there's no reason not to support it).

* 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.

Instead of passing the uniform array as an argument to the transfer function evaluation function, create two separate transfer function evaluation functions that read the uniforms directly.
