Summary: So far KWin does not know which Compositors the platform actually supports. This results in KWin happily trying to use the OpenGL compositor on fbdev or the QPainter compositor on hwcomposer although that is obviously going to fail as the platform doesn't support this. By adding a pure virtual method all Platforms can define what they support. In a later step the Compositor can use this to create an appropriate scene and also perform proper fallback handling in case the scene creation fails. Test Plan: Compiles Reviewers: #kwin, #plasma Subscribers: plasma-devel, kwin Tags: #kwin Differential Revision: https://phabricator.kde.org/D8316
