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.

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

This adds a window hint string for the xdg_toplevel::app_id, which is
used by desktop environments to connect windows with application icons
and other information. This is similar to the WM_CLASS property on X11.
A few very minor fixes were done by @elmindreda during merge.

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.

The Wayland backend now requires xkbcommon-compose, which was added in
version 0.5.0. xkbcommon 0.5.0 was released in 2014.
This removes the non-composing fallback path for text input.
This removes the GLFW_VULKAN_STATIC CMake option and the
_GLFW_VULKAN_STATIC configuration macro and replaces them with the
glfwInitVulkanLoader function, allowing a single library binary to
provide both behaviors.
This is based on the design from PR #1374 by @pmuetschard.

This more or less restores the original custom layout where the TOC is
on the right side, with a CSS workaround added for portrait orientation.
The indentation of sub-lists in the TOC has been decreased.
The sizes of HTML headings and the "h0" div generated for each Doxygen
page have been adjusted to look better together now that they can meet.
A few headings have been shortened to fit better in the narrower TOC.
This was especially bad in the window guide, where the TOC ended up
having "Window related hints" and "Windows specific window hints" close
to one another.
This commit only fixes headings. There are likely issues in the actual
text as well.
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.

This adds the glfwInitAllocator function for specifying a custom memory
allocator to use instead of the C runtime library.
The allocator is a struct of type GLFWallocator with fields
corresponding to malloc, realloc and free, while the internal API
corresponds to calloc, realloc and free.
Heap allocation calls are filtered before reaching the user-provided
functions, so deallocation of NULL and allocations of zero bytes are not
passed on, reallocating NULL is transformed into an allocation and
reallocating to size zero is transformed into deallocation.
The clearing of a new block to zero is performed by the internal
calloc-like function.
Closes#544.

This adds the GLFW_LIBRARY_TYPE CMake cache variable, which allows users
and higher-level projects to set what type of library GLFW is built as.
When not empty, this value overrides the standard BUILD_SHARED_LIBS
option for GLFW while still allowing it to control the type of other
libraries in a larger project.
This also allows building GLFW as an object library without adding dummy
source files (as required by Xcode) or producing unused library
binaries.
Projects using CMake 3.12 or later can link the resulting GLFW object
library normally using target_link_libraries.

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.

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.
