The reviewers were right to question an inflate() so deep in the code--in exploring this more I found this clip bug affects Skia and CG differently. I've played with some other ways of fixing this but the end result is that this patch here is too simplistic.

I'd like to abandon my approach here for now, as it's clear there are at least a couple bugs that I need to tackle separately.

(Some details)
Skia's clip() is not antialiased, which causes the clipped aliasing on all non-integer-aligned shapes. This is actually different from the border bug on semi-transparent lines, which seems to affect CG and Skia, but was erroneously "fixed" by inflating the repaint rect.
