We don't have anything drawing colors outside sRGB,
but now that we've got SkPaint::setColor4f(), that's easy.
Looks like we have lots of work to do.
Pin GrColor4f floats before converting to unsigned.
Underflowing floats would get pinned to 255 spuriously
instead of to 0. I think this fixes the failing CQ
bot, and the white square problem.
