* 12to11.c (XLMain): Initialize timestamp tracking. * 12to11.man: Document *.useDirectPresentation resource. * atoms.c (names): Add _NET_WM_PID and _NET_WM_PING. (XLInitAtoms): Likewise. * compositor.h (struct _RenderFuncs): Update doc of cancel_presentation. (enum _FrameMode): Add ModeNotifyDisablePresent. (struct _XdgRoleList, struct _XdgWmBase): New structs. * frame_clock.c (StartFrame): Return if the clock was really started. (XLFrameClockStartFrame): Likewise. (XLInitFrameClock): Move Sync extension initialization to InitTime. * picture_renderer.c (struct _PresentCompletionCallback) (struct _PictureTarget, InitSynchronizedPresentation) (InitRenderFuncs, TargetFromDrawable, DestroyRenderTarget) (PresentToWindow, CancelPresentationCallback, AddRenderFlag) (HandlePresentCompleteNotify): Link structure on target. When synchronized presentation is enabled, use the approriate msc to present, and record the last known msc. * run.c (HandleOneXEvent): Handle timestamp events. * subcompositor.c (SubcompositorUpdate): Note frame with ModeNotifyDisablePresent. (FindSystemCounter, ValueToScalar, ScalarToValue, StartAlarms) (HandleAlarmNotify, HandleOneXEventForTime, InitTime): New functions. * xdg_surface.c (struct _XdgRole): New fields `link' and `wm_base'.
