Mike Klein 04e10da836 clamp to premul when reading premul sRGB 
It's pretty easy to start with sound premultiplied linear floats, pack those to sRGB encoded bytes, then read them back to linear floats and find them not quite premultiplied, with a color channel just a smidge greater than the alpha channel.  This can happen basically any time we have different transfer functions for alpha and colors... sRGB being the only one we draw into.

This is an annoying problem with no known good solution.  So apply the clamp hammer.

These new calls on SkRasterPipeline should make it impossible to get wrong.
