2020-08-25present/wnmd: Execute copies at target_msc-1 alreadyMichel Dänzer1-8/+18
It always takes one update cycle for the copy to become visible on the host windowing system, so waiting for the target MSC resulted in 1 cycle delay. We re-use the idle list for copies which were executed but need their completion event sent. Fixes black seams when resizing the "Builder" sub-window of GDK_BACKEND=x11 gtk4-demo on Xwayland (see https://gitlab.gnome.org/GNOME/mutter/-/issues/1290#note_873557). Unfortunately, this cannot completely fix the seams with apps which queue up multiple frames in advance, since there's always at least one queued frame corresponding to the old window size. But it should at least help a little in that case as well. v2: * Bug fix: Don't update exec_msc in present_wnmd_check_flip_window.

2020-07-24present: Check valid region in window mode flipsRoman Gilg1-4/+6
For Pixmap flips to have well defined outcomes the window must be contained by the valid region if such region was specified. The valid region is inserted as an argument to the check in window mode. Setting this argument is missing in screen mode as well but we ignore it for now and only add it to window mode. It seems there are none or only very few clients actually making use of valid regions at the moment. For simplicity we therefore just check if a valid region was set by the client and in this case do never flip, independently of the window being contained by the region or not.

2020-07-22present: Idle vblanks any time in window modeRoman Gilg1-0/+7
With the newly introduced separate API method for idling a presented Pixmap in window mode we can simplify the logic by allowing calls to it at any point in time.

2020-07-22present: Notify via distinct API functions in window modeRoman Gilg2-13/+46
Notifying Present about events' states was done prior with the single function present_wnmd_event_notify just like in screen mode. But it is more intelligible if at least in window mode we make use of three different functions with names that directly indicate what their purpose is: * present_wnmd_event_notify only for queued events feedback. * present_wnmd_flip_notify for when a presentation occured (flip). * present_wnmd_idle_notify for when the Pixmap of the event can be reused. This is an API-breaking change in regards to window mode. DDX written against the previous version won't work anymore. It is assumed that there only exists the XWayland DDX at the moment using the window mode such that this is not an issue for the overall ecosystem. Signed-off-by: Roman Gilg <subdiff@gmail.com>

So if we don't free them first, they're leaked. Also drop the call to present_wnmd_set_abort_flip, which just sets a flag in struct present_window_priv and thus can't have any observable effect after present_destroy_window.

However, `xwl_present_get_crtc()` can return `NULL` under some circumstances, which would cause an unexpected termination of Xwayland in such a case, caused by the assertion failure being triggered.
