2b3f919b60 Wayland: Add support for fractional scaling
This adds basic support for fractional-scale-v1.

Note that this introduces a potential discrepancy between window and
monitor content scales.

a9cc7c7260 Add GLFW_SCALE_FRAMEBUFFER window hint
This adds the GLFW_SCALE_FRAMEBUFFER window hint, enabling control of
framebuffer scaling across Wayland and macOS.  On macOS, this window
hint is a new name for GLFW_COCOA_RETINA_FRAMEBUFFER, and both hint
names will modify the same hint.

This is now a more symmetric counterpart to GLFW_SCALE_TO_MONITOR and,
weirdly, they each apply neatly to half of the supported platforms.

This commit is mostly documentation updates to better integrate and
contrast these two scaling mechanisms.

a360198f8f Wayland: Implement glfwFocusWindow
This implements window focus requests via the xdg-activation-v1
protocol.  These requests will likely only work when another window of
the same application already has input focus, but that isn't unlike the
behavior of other platforms.

The GLFW_FEATURE_UNAVAILABLE error has been removed from this function
for now.

9317970243 Wayland: Implement glfwRequestWindowAttention
This implements window attention requests via the xdg-activation-v1
protocol.

This was updated by @ elmindreda to work with recent Wayland related
 changes to the main branch:
 - Switched to current way of handling Wayland protocol files
 - Added the xdg-activation-v1.xml protocol file to deps/wayland
 - Added missing macros to rename protocol interface globals

The protocol file was copied from wayland-protocols 1.33.

2590d4cdd4 Wayland: Enable platform by default
This changes the default platform for Unix-like systems (other than
macOS) from only X11 to Wayland and X11.  It also removes the backward
compatibility with the older GLFW_USE_WAYLAND CMake option.

If a bisect took you here because your build broke, hello, sorry, set
the GLFW_BUILD_WAYLAND or GLFW_BUILD_X11 CMake option to disable the
associated platform.

This can be done when configuring GLFW with CMake, from a higher-level
CMakeLists.txt if GLFW is part of your project, or at any point after
configuration by updating the CMake cache with the command-line tool or
the GUI.

The next step is to make Wayland the run-time default when enabled, but
that will hopefully not break any builds.

2c3eb75748 Wayland: Remove dependency on wayland-protocols
This brings the latest released versions of all used Wayland protocol
files into this repository, removing the need for the user to arrange
a sufficiently new version of wayland-protocols.

The wayland.xml protocol file was copied from wayland 1.22.0.
The additional protocol files were copied from wayland-protocols 1.32.

Because of how files are moved and renamed inside the wayland-protocols
repository, it will not always be possible to update all our protocol
files from a single release without also potentially updating related
code (acceptable) and prematurely breaking compatibility with
compositors that still only support an earlier incompatible version
(unacceptable).

The macro in src/CMakeLists.txt has been modified to hopefully make it
easier to add new protocol files.  This made it necessary to change the
name of a few of the generated header files.

9959dc69ca Improve documentation relating to key tokens
Shifted the documentation away from the term 'named keys' as something
different than keys that glfwGetKeyName will return a name for.  The
already existing term 'key token' should now be used to refer to the
GLFW_KEY_* constants.

The associated term 'named mouse button' was also replaced with
'supported mouse button'.

The parts explaining which key tokens will return a valid scancode from
glfwGetKeyScancode have hopefully been clarified.  This issue was
reported in #2055.

The GLFW_KEY_UNKNOWN constant has been moved out of the list of key
tokens to simplify and hopefully clarify the related documentation.

Various other keyboard key related edits were made, hopefully resulting
in improvements.

fbdb53b9ca Wayland: Add initial support for libdecor
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.

ef6c9d8b4f Wayland: Fix window opacity on older systems
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.

0f9a9578f3 Add window hints for initial position
This adds window hints for the initial position, in screen coordinates,
of a window.  The special value GLFW_ANY_POSITION means the window
manager will be allowed to position the window.

It is not possible to set window positions on Wayland and GLFW will
always behave as if these hints are set to GLFW_ANY_POSITION.

cd22e28495 X11: Fix empty event race condition with a pipe
There is a seemingly unavoidable race condition when waiting for data on
the X11 display connection, as long as any other thread is also making
Xlib calls.  The event data we are waiting for could be read by the
other thread as part of looking for the reply to its request, before our
poll has begun.

This commit replaces the X11 event sent by glfwPostEmptyEvent with
writing to an unnamed pipe.  The race condition remains if other Xlib
calls are made on other threads, but glfwPostEmptyEvent should now be
race-free.

This commit is based on work by pcwalton, OlivierSohn, kovidgoyal and
joaodasilva.

56a4cb0a3a Add runtime platform selection
This adds compile-time support for multiple platforms and runtime
detection of them.  Window system related platform functions are now
called from shared code via the function pointer struct _GLFWplatform.

The timer, thread and module loading platform functions are still called
directly by name and the implementation chosen at link-time.  These
functions are the same for any backend on a given OS, including the Null
backend.

The platforms are now enabled via CMake dependent options following the
GLFW_BUILD_<platform> pattern instead of a mix of automagic and ad-hoc
option names.  There is no longer any option for the Null backend as it
is now always enabled.

Much of the struct stitching work in platform.h was based on an earlier
experimental branch for runtime platform selection by @ronchaine.

Every platform function related to windows, contexts, monitors, input,
event processing and Vulkan have been renamed so that multiple sets of
them can exist without colliding.  Calls to these are now routed through
the _glfw.platform struct member.  These changes makes up most of this
commit.

For Wayland and X11 the client library loading and display creation is
used to detect a running compositor/server.  The XDG_SESSION_TYPE
environment variable is ignored for now, as X11 is still by far the more
complete implementation.
