If the clip was a rect, what about this begin/end
sohanjg
2014/08/06 14:09:26
yes, for rect clip, we would have got a non-empty

I don't understand, the opaque rect is non-empty?

hmm..once we set context.clipPath, it seems we can

You can clipRect with kReplace_Op for instance?

I have updated the test and used rect device clip
