jumper, bilinear and bicubic sampling stages
This splits SkImageShaderContext into three parts:
- SkJumper_GatherCtx: always, already done
- SkJumper_SamplerCtx: when bilinear or bicubic
- MiscCtx: other little bits (the matrix, paint color, tiling limits)
Thanks for the snazzy allocator that allows this Herb!
Both SkJumper and SkRasterPipeline_opts.h should be speaking all the
same types now.
I've copied the comments about bilinear/bicubic to SkJumper with little
typo fixes and clarifications.
