Eliminates SkFlattenable{Read,Write}Buffer, promoting SkOrdered{Read,Write}Buffer
a step each in the hierarchy.
What used to be this:
SkFlattenableWriteBuffer -> SkOrderedWriteBuffer
SkFlattenableReadBuffer -> SkOrderedReadBuffer
SkFlattenableReadBuffer -> SkValidatingReadBuffer
is now
SkWriteBuffer
SkReadBuffer -> SkValidatingReadBuffer
Benefits:
- code is simpler, names are less wordy
- the generic SkFlattenableFooBuffer code in SkPaint was incorrect; removed
- write buffers are completely devirtualized, important for record speed
This refactoring was mostly mechanical. You aren't going to find anything
interesting in files with less than 10 lines changed.
