When we shrink a path, we might relocate its underlying arrays. Doing so would invalidate any outstanding Iterators. The caller must handle this for its path object, but there may be copies elsewhere, which have just ref'd the underlying arrays. To keep these copys' iterators alive, we defensively "copy-on-write", so as to not relocate their buffers. Incidentally, update SkContourMeasureIter's constructor to clarify that it is iterating through its copy of the path, and not the original.
