Separate source and header files for MutterWindow compositor.c: Move MutterWindow code to mutter-window.c; rename map_win() to mutter_window_map(), etc. mutter-window-private.h: New private header file for MutterWindow functions used internally to the compositor. compositor-mutter.h: Move MutterWindow declarations to mutter-window.h; move a couple of private functions to compositor-private.h compositor-private.h: Move MetaCompScreen declaration to here: Conceptually it's private to compositor.c, but MutterWindow manipulates some of the lists directly for now. mutter-plugin.c compositor.c: Don't call mutter_window_effect_completed() for MUTTER_PLUGIN_SWITCH_WORKSPACE, but use a new mutter_switch_workspace_completed(), since the window is just used to identify a screen. http://bugzilla.gnome.org/show_bug.cgi?id=587251

#include <X11/extensions/Xfixes.h>
compositor: Make sure _NET_WM_FRAME_DRAWN timestamp has the right scope The timestamp sent with _NET_WM_FRAME_DRAWN should be in "high resolution X server timestamps", meaning they should have the same scope as the built in X11 32 bit unsigned integer timestamps, i.e. overflow at the same time. This was not done correctly when mutter had determined the X server used the monotonic clock, where it'd just forward the monotonic clock, confusing any client using _NET_WM_FRAME_DRAWN and friends. Fix this by 1) splitting the timestamp conversiot into an X11 case and a display server case, where the display server case simply clamps the monotonic clock, as it is assumed Xwayland is always usign the monotonic clock, and 2) if we're a X11 compositing manager, if the X server is using the monotonic clock, apply the same semantics as the display server case and always just clamp, or if not, calculate the offset every 10 seconds, and offset the monotonic clock timestamp with the calculated X server timestamp offset. This fixes an issue that would occur if mutter (or rather GNOME Shell) would have been started before a X11 timestamp overflow, after the overflow happened. In this case, GTK3 clients would get unclamped timestamps, and get very confused, resulting in frames queued several weeks into the future. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1494

#include "clutter/clutter.h"
compositor: Expose the MetaCompositorView in before_paint () vfunc The idea is that the state of the MetaCompositorView shall be up-to-date only in specific scenarios, thus allowing operations performed on it to be queued and aggregated to be handled in the right time, and only if they are still necessary. For example, in a following commit, the top window actor in each view will be planned (if needed) only once before painting a frame, rendering the top window actor in the MetaCompositorView potentially stale in all other times. Similarly, if a MetaCompositorView is destroyed before the beginning of the frame, a queued operation to update its top window actor can be discarded. As an interface segragation measure, and as part of an attempt to avoid the use of g_return_if_fail () to check the validity of the MetaCompositorView's state in multiple places (which is still prone to human error), the interfaces through which a MetaCompositorView is made available would only ones where it's state is gurenteed to be up-to-date. Specifically, this commit gurentees that the state of the MetaCompositorView would be up-to-date during the before_paint () and after_paint () vfuncs exposed to child classes of the MetaCompositor. The frame_in_progress variable will be used in a following commit to guarantee that the MetaCompositorView's state is not invalidated during this time.

later: Make MetaCompositor the owner of the MetaLaters state Since the order of destruction during MetaDisplay tear down is a bit unordered, there are pieces that try to destruct its compositing dependent pieces (i.e. queued MetaLater callbacks) after MetaCompositor has been cleaned up, meaning we need to put some slightly awkward NULL checks to avoid crashing. https://gitlab.gnome.org/GNOME/mutter/merge_requests/798

display: Initialize MetaCompositor in two steps MetaCompositor is the place in mutter that manages the higher level state of compositing, such as handling what happens before and after paint. In order for other units that depend on having a compositor instance active, but should be initialized before the X11 implementation of MetaCompositor registers as a X11 compositing manager, split the initialization of compositing into two steps: 1) Instantiate the object - only construct the instance, making it possible for users to start listening to signals etc 2) Manage - this e.g. establishes the compositor as the X11 compositing manager and similar things. This will enable us to put compositing dependent scattered global variables into a MetaCompositor owned object. For now, compositor management is internally done by calling a new `meta_compositor_do_manage()`, as right now we can't change the API of `meta_compositor_manage()` as it is public. For the next version, manual management of compositing will removed from the public API, and only managed internally. https://gitlab.gnome.org/GNOME/mutter/merge_requests/798

compositor: Keep track of the top window actor on each view First, add logic in MetaCompositorView to find topmost visible MetaWindowActor on its view, and expose it through a new API. Then, queue an update to find the top MetaWindowActor of each MetaCompositorView in the following cases: 1. The MetaCompositor is in its initial state. 2. The window stack order has changed. 3. A window has changed its visibility. 4. A "stage-views-changed" signal was emitted for a MetaWindowActor. Finally, perform the queued update in meta_compositor_before_paint (), and assert that an update isn't queued during painting. This ensures that the top window actor in the MetaCompositorView remains up-to-date and available to child classes of MetaCompositor throughout the entire paint stage.
