Review Comment:
`calSamplesChanged` before check `changed` can ensure that all the samples
has been updated at once.
For examle, if a composite contains A and B samples and these two samples
are changed. If `calSamplesChanged` before check `changed` can update all the
flags both in A and B. Thus, one time `refresh` can refresh all.
