This is partly based on the implementation of libdecor support in
PR #1693 by @ christianrauch.
Where available, the libdecor library is loaded at init and becomes the
preferred method for window decorations. On compositors that support
XDG decorations, libdecor in turn uses those. If not, libdecor has
a plug-in archtecture and may load additional libraries to either use
compositor-specific decorations or draw its own.
If necessary, support for libdecor can be disabled with the
GLFW_WAYLAND_LIBDECOR init hint. This is mostly in case some part of
the dynamic loading or duplication of header material added here turns
out to cause problems with future versions of libdecor-0.so.0.

This was adapted to 3.3-stable from
fbdb53b9ca.
On systems lacking the EGL_EXT_present_opaque extension, some
compositors treat any buffer with an alpha channel as per-pixel
transparent.
This commit ignores any EGLConfig with an alpha channel if the extension
is missing and the window is created with GLFW_TRANSPARENT_FRAMEBUFFER
set to false.
This is technically not a breaking change since GLFW_ALPHA_BITS is not
a hard constraint, but it is still going to inconvenience anyone using
the framebuffer alpa channel to store other kinds of data.

The cursor theme was only loaded if the chosen seat had a mouse
(wl_pointer) during initialization. If a mouse was connected only after
glfwInit, there would be no cursor theme but the rest of the cursor
related code assumed one had already been loaded.
This also moves the details of cursor theme loading out into a separate
function to declutter platform init.
Because the original cursor theme loading code checked whether we got
a wl_shm, and because the rest of the code just assumes we have
a wl_shm, initialization will now fail if there isn't one.

Whenever GLFW changed the window style mask, a new mask was created
from scratch based on the attributes set on the GLFW window object.
This caused us to potentially clear unrelated window style bits.
This was always wrong but became a critical issue when Cocoa began
throwing an exception if an application cleared the
NSWindowStyleMaskFullScreen while the window is in macOS fullscreen.
This commit reworks all style mask editing so it only changes the
relevant bits, preserving all others.
This is only a narrow bug fix to prevent crashes, intended for the
stable branch. Our interaction with macOS fullscreen is still very
poor. The next step after this is a set of patches that improve the
interaction between the current API and macOS fullscreen.

The reasoning here is that glfwRestoreWindow will change nothing for
a windowed non-resizable window on Cocoa, and silently refusing to
maximize seems slightly more like something other platforms would do.
This is possibly either the right thing to do or the wrong one.

On a compositor that supports server-side decorations, they were always
enabled in windowed mode, even if GLFW_DECORATED was cleared.

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.

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.

The aspect ratio was applied during resize but any call to
glfwSetWindowAspectRatio emitted a GLFW_FEATURE_UNIMPLEMENTED error.

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.
(cherry picked from commit e37ba80b13)
GLFW would report a monitor as connected each time its wl_output
received an update, for example if its scale changed.
This would also cause the monitor to be added to the monitor array
again, causing glfwTerminate to segfault when it attempted to destroy
its already destroyed wl_output.

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
(cherry picked from commit a7b6f35500)
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 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

By default, the glfw3native.h header will include the platform-specific
headers necessary for the return types of GLFW native access functions.
Sometimes it is preferrable to declare those types
This commit adds support for the GLFW_NATIVE_INCLUDE_NONE macro, which
when defined disables the inclusion of all platform-specific headers.

GLFW did not restore the previous Xlib error handler when removing its

This commit saves and restores the previous error handler.
None of this is thread-safe or could ever be.

This avoids glfwCreateWindow emitting GLFW_PLATFORM_ERROR 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 code assumed that at least some data would be received via the INCR

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.

Emitting an error for one specific type of failure in retrieving the

(cherry picked from commit 955fbd9d26)
Operations that take an instance handle should be passed the handle of
whatever module we are inside instead of blindly passing the handle of
the executable.
This commit makes GLFW retrieve its own instance on initialization.
This makes the most difference for window classes, which are
per-instance. Using the executable instance led to name conflicts if
there were several copies of GLFW in a single process.
Note that having this is still a bad idea unless you know what things to
avoid, and those things are mostly platform-specific. This is partly
because the library wasn't designed for it and partly because it needs
to save, update and restore various per-process and per-session settings
like current context and video mode.
However, multiple simultaneous copies of GLFW in a single Win32 process
should now at least initialize, like is already the case on other
platforms.
