This protocol is part of the core Wayland, but it is pretty badly
designed and is missing quite a few features, and is in the process of
being phased out in compositors. Its support in GLFW requires
duplicating pretty much every single window management codepath.
This bumps the required compositor versions to the ones which have
implemented xdg-shell, approximately two years ago, which seems sensible
to me.
This renames 'raw input' to 'raw mouse motion' as there are other kinds
of raw input. The update path is restructured to avoid reinitializing
all of disabled cursor mode. Modification of shared state is moved out
into shared code. Raw mouse motion is disabled by default for
compatibility.
Related to #1401.
We now keep track of the fullscreen and activated state and only iconify
if we were previously fullscreen and now we are either not fullscreen or
not activated anymore.
This is the proper way to do it, compared to the previous hack where we
didn’t iconify only if it was the first configure event received.
This allows compositors which prefer to draw the decorations around
clients to do so, rather than letting GLFW draw its own decorations.
The appearance is thus entirely subject to the compositor used, but
should generally be better than the current solid colour decorations we
have, which we continue to use when the compositor doesn’t support this
protocol or tells us to draw the decorations ourselves.
This new protocol has been tested against wlroots’s rootston compositor.
Fixes#1257.
This allows the compositor to avoid having to setup and teardown a
SIGBUS signal handler whenever it needs to read from this surface, as it
knows we won’t be able to shrink the file and so doesn’t have to protect
against that.
This codepath will only be used on Linux ≥ 3.17 with glibc ≥ 2.27, and
possibly other kernels and libc. The former code will continue to be
used as a fallback, either if memfd_create() fails or if it isn’t
available.
This protocol matches desktops much better than the deprecated
wl_shell, fixing a bunch of race conditions, removing undefined
behaviour, adding missing features, and generally providing a much more
user-friendly experience.
Since most compositors don’t support it yet, the wl_shell_surface role
is kept as fallback for now.
