The KWin::TimeLine class was only a small wrapper around QTimeLine
without adding anything to QTimeLine what is not present in QTimeLine.
The initial idea was to make it possible to provide more curve shapes.
This is now obsoleted by Qt shipping more useful curves with QTimeLine.
So let's clean up a little bit and use QTimeLine directly instead of
the small wrapper.
All effects are adjusted to use QTimeLine directly.
First a signal is emitted when the user starts a move/resize operation.
During the move/resize operation each geometry change emits an update signal.
Last but not least a finish signal is emitted.
This eliminates the specific method for geometry updates in drawbound resize
mode.
Client and Unmanaged use a signal to notify that they are about to be closed.
The EffectsHandlerImpl is connected to those signals and emits the appropriate
windowClosed signal to which the effects are connected.
perfectionist people that want to move a window to the exact center of
the screen but can never get close enough to it for the automatic
snapping to trigger. OpenGL-only for now, gave up on XRender, if anyone
can get it to work go for it.
