When showing a window that had already been shown once (and so already
had its shell objects), GLFW would attach a new buffer and commit it
before waiting for the next configure event. This was a violation of
the XDG shell protocol.
This was allowed to work as intended on GNOME and KDE without error.
However wlroots based compositors would (correctly) emit an error.
Unfortunately, I haven't been able to find a way to get both KDE, GNOME
and Sway to send the configure event we need in order to map the
wl_surface again while keeping our existing shell objects, so with this
commit we now create them for each call to glfwShowWindow and destroy
them for each call to glfwHideWindow.
Fixes#1268
If a window was created as maximized, or created as hidden and then
iconified or maximized before first being shown, that state was lost and
the window was shown as restored.
Window iconfication and maximization events were being emitted before
xdg_surface::configure, making it possible for user code to indirectly
commit surface changes from those event callbacks before
xdg_surface::ack_configure.
This postpones those events until after the ack has been sent.
Content scale events would be emitted when a window surface entered or
left an output, but not when one of a window's current outputs had its
scale changed.
This is a temporary local fix to have updates to GLFW_DECORATED mostly
work as intended. The whole decoration state machine needs to be
restructured, but not by this commit.
The size limits set on our XDG surface did not include the sizes of the
fallback decorations on all sides, when in use. This led to its content
area being too small.
Related to #2127
The handler for xdg_toplevel::configure treated the provided size as the
content area size when instead it is the size of the bounding rectangle
of the wl_surface and all its subsurfaces.
This caused the fallback decorations to try positioning themselves
outside themselves, causing feedback loops during interactive resizing.

The surface was resized and the size event was emitted before we had
sent xdg_surface::ack_configure. If user code then called some GLFW
function that commited the surface, those changes would all get applied
to the wrong configure event.
This postpones size changes until after the ack.
The internal maximization state was not updated when an event was
received that the user had changed the maximization state of a window,
and no maximization events were emitted.
This affected both the GLFW_MAXIMIZED attribute and glfwRestoreWindow.
These changes make GLFW fullscreen more consistent, but unfortunately
also make GLFW even more oblivious to user-initiated XDG shell
fullscreen changes.
Fixes#1995
The modifier bits for lock keys were only set when the corresponding key
was reported as held down or latched, but not when it was released and
locked.
This avoids glfwCreateWindow emitting GLFW_FEATURE_UNAVAILABLE or
GLFW_FEATURE_UNIMPLEMENTED on Wayland because shared code was calling
unimplemented or unavailable platform functions during final setup.
It also makes it consistent with the final setup of full screen windows.
The Wayland backend was the only one where half the window and input
related code was in the init module. As those bits want to share more
utility code with the window module, the interface between them grows.
To prevent that, this gathers nearly all window and input related code
into the window module.
The code assumed that all data offers were selections that supported
plaintext UTF-8.
The initial data offer events are now handled almost tolerably. Only
selection data offers are used for clipboard string and only if they
provide plaintext UTF-8. Drag and drop data offers are now rejected as
soon as they enter a surface.
