Martin Gräßlin	823deba1d6	[kwin/scene_qpainter] Use size of shell surface as back buffer size Most important connect to the surface size changed signal so that we can create a new back buffer which matches the size of the surface.	12 years ago
Martin Gräßlin	92761e9e30	[kwin] Fix ifdefs for Wayland With the switch to FindWayland from ECM WAYLAND_FOUND was no longer set thus the ifdef didn't work. Now we use HAVE_WAYLAND and HAVE_WAYLAND_EGL.	12 years ago
Martin Gräßlin	1be3a7a9f0	Introduce a method shouldUseWaylandForCompositing() in KWin::Application Returns true if the OperationMode requires KWin to composite to a Wayland surface. This replaces the checks for the WaylandBackend or env variable used so far in the construction of the Scene.	12 years ago
Martin Gräßlin	0c559c163d	New QPainter based compositor called SceneQPainter This compositor uses only the QPainter API to perform rendering. The window's X Pixmap is mapped to a QImage using XShm. As rendering backend a QImage is used. The new compositing type "QPainterCompositing" is introduced. Effects need to be adjusted to explicitly check the compositing type and no longer assume the compositing type is XRender if it's not OpenGL. This compositor can be selected with using "Q" as the value for KWIN_COMPOSE env variable or setting the config value to "QPainter". The GUI is not yet adjusted to select this compositor. The QPainter scene provides currently the following features: * 2D transformations (translation and scalation) * opacity modifications * rendering of decorations (new PaintRedirector sub class) * rendering of shadows * rendering of effect frames * rendering to a Wayland surface The following features are currently not provided: * saturation changes * brightness changes * 3D transformations * rendering to X Overlay window * offscreen rendering (e.g. needed for screen shot effect) * custom rendering in the effects to the current back buffer	12 years ago
