D7669: Make AbstractEglBackend a QObject

[Martin Flöser]

graesslin created this revision.
Restricted Application added a project: KWin.
Restricted Application added subscribers: kwin, plasma-devel.

REVISION SUMMARY
  Several of the subclasses are already derived from QObject.
  
  The main reason is that the class should be moved out of KWin core in
  order to move the OpenGL scene into a plugin. As Compositor calls into
  the AbstractEglBackend to unbind the wayland display this creates a
  problem which is easily solved by turning the AbstractEglBackend into a
  QObject and connect to the signal emitted by the Compositor.
