Currently KWin is combining modesets with presentation, which causes problems when multiple monitors are used and crtcs need to be switched around, because taking away a CRTC from another output causes the driver to disable the other output. In order to avoid such problems, delay presentation until all pipelines are ready to present and then do a modeset with a single atomic commit. To process the resulting page flip events properly this commit also ports KWin to page_flip_handler2 and changes how the pageFlipped and notifyFrameFailed signals are processed.
