Summary: Source code reorganization: The base class AbstractBackend got renamed to Platform, thus the "backends" are "platforms" now. As they are plugins they should go together with other KWin plugins which are nowadays in the folder plugins. So new location is plugins/platforms/ Reviewers: #plasma, sebas Subscribers: plasma-devel Projects: #plasma Differential Revision: https://phabricator.kde.org/D1353
