The list of compile-time dependencies on FreeBSD lacked evdev-proto.
Unlike on Linux, the input-event-codes.h header file was not implicitly
included on FreeBSD.
Fixes#2445
This was adapted to 3.3-stable from
51920ede68.
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.

Passing a context-less window to a function that requires a context only
emits a harmless GLFW_NO_WINDOW_CONTEXT error.

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.

This fixes spelling, grammar and punctuation issues, missing words and
stray words across the documentation. A confusing sentence was removed
from the tutorial.

(cherry picked from commit 2e12ef00bb)
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.

In the compile guide, the "Dependencies for Linux and OSMesa" section
looks to be one level too high in the hierarchy. I've moved it to be in
line with the similarly-named sub-sub-sections.

Some URLs in the documentation were overlooked during the switch to

New code should use GL_KHR_debug instead but it's not as good an example

This makes USE_MSVC_RUNTIME_LIBRARY_DLL update the directory scope
CMAKE_MSVC_RUNTIME_LIBRARY variable instead of CMAKE_C_FLAGS on CMake
3.15 and later.
Solution proposed by @moritz-h.

(cherry picked from commit f4a7329604)
On Windows 7, when GLFW framebuffer transparency and the DWM are enabled
but DWM transparency is disabled (i.e. when the Transparency setting is
disabled under Personalization > Color), the contents of the framebuffer
is combined with the last frame using additive blending instead of
replacing the previous contents.
This commit limits GLFW framebuffer transparency on Windows 7 to when
DWM transparency is enabled, removing the previous workaround of setting
a layered window color key that led to rendering artifacts.
Fixes#1512.

Re-worded documentation for the `GLFW_OPENGL_DEBUG_CONTEXT` window hint
to avoid implying that it only applies to OpenGL contexts. Added a link
to the relevant Khronos extension description.
Closes#1720.
(cherry picked from commit 8a69a0d7e5)
The documentation claims that any extension loader library header
included before the GLFW one will prevent the inclusion of the
default OpenGL header. In reality this only worked if the loader
defined the canonical desktop OpenGL __gl_h_ inclusion guard and even
then relied on the OpenGL header to detect this.
This is the companion to 105cf32e0b, which
added the preprocessor logic to check for many known OpenGL and OpenGL
ES inclusion guards and not even attempt to include the default header
if any are present.
Some clarification of the language around header inclusion has also been
attempted, including making GLFW_INCLUDE_NONE more prominent.
Fixes#1695.
