annotate pyink/domview.py @ 1265:ca301f6abef7

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Support undo for insert key frame/rm keyframe. We will refresh all layers and scenes since it is not feasible to collect these changes and update the layers and scenes. We may scan two level only in the future to improve the performance.
