* default impl of appendStages now calls shaderContextGravatar Mike Reed2017-06-02
| | | | | | | | | | | | | | | | | | this is approximately a revert of https://skia-review.googlesource.com/c/17768/ I propose if/when we want to experiment with a fast-path for coherent shaders (e.g. 2-color linear gradients, up-scaling images) that we just create a new mechanism for shaders to opt into that, knowing that it will be driven by the rasterpipeline (and never by the old context convention). This CL now makes it legal/clear that a new shader subclass can *just* implement stages for raster, and never needs to make a context.

* have shaders that need seed_shader call it themselvesGravatar Mike Klein2017-06-01
| | | | | | | | | | | | This ought to make compose shader and our sprite blitter a bit more efficient. Compose shader can simply re-seed instead of saving the xy values off to a buffer. The sprite blitter doesn't need xy at all.

* add stages to colorfiltershaderGravatar Mike Reed2017-05-31
| | | | | | | | | | | | Interestingly, this public api (makeWithColorFilter) is only used internally by the legacy raster blitters. Perhaps we could remove/hide it? ... and that API is the only way we create one of these shaders.

* assume sRGB transfer function on untagged imagesGravatar Mike Klein2017-05-31
| | | | | | | | | | | | | | | | This has been a long time coming. There are probably one or two more places we'd want to do this on the CPU side too, but it's a start. Somewhat seriously, this is my proposed fixed for colorburn + xfermodes2. We're not interpreting the red or green images sensibly.
