Git commit e6e9fea57bc9b57b5b07810e8bcf2b94ec65b954 by Dmitry Kazakov. Committed on 09/09/2019 at 15:28. Pushed by dkazakov into branch 'master'. Fix crash when liquify transform is started too quickly Basically, we shouldn't initiate any transform action until the transform strategy has finished preparing tool initialization (which is flagged by setting m_transform.rootNode()). All user actions happened before the initialization should be ignored (he doesn't have any feedback anyway).
