Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Improve resource management for coords, shapes and paints. - Make paint to use weak reference to release resource before collected. - Call Persistent<Object>::Dispose() before deleting the handle variable. Dispose() will real release Persistent handle. Handle variable is just a pointer to the handle.
