Michel Dänzer 1f7527bbc4 clutter/frame-clock: Fix handling of equal next_presentation_time_us
This can happen with the native backend if the previous frame clock
dispatch didn't result in any KMS update, e.g. because it was triggered
by an input event, but the HW cursor didn't need updating on the stage
view. (This is likely to happen on some out of multiple stage views,
but might be possible even with a single stage view if the cursor isn't
visible)

We would previously delay next_presentation_time_us by one refresh
interval in this case, which could result in spuriously leaving one
refresh cycle unused.

Mutter

Mutter is a Wayland display server and X11 window manager and compositor library.

When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.

When used on top of Xorg it acts as a X11 window manager and compositing manager.

It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.

Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork of Clutter, a scene graph and user interface toolkit.

Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.

Git messages

Commit messages should follow the GNOME commit message guidelines. We require an URL to either an issue or a merge request in each commit. Try to always prefix commit subjects with a relevant topic, such as compositor: or clutter/actor:, and it's always better to write too much in the commit message body than too little.

Default branch

The default development branch is main. If you still have a local checkout under the old name, use:

git checkout master
git branch -m master main
git fetch
git branch --unset-upstream
git branch -u origin/main
git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/main
