7da3e52c86 Win32: Fix GLFW_MOUSE_PASSTHROUGH dropping events
Returning HTTRANSPARENT from WM_NCHITTEST does cause the window to be
transparent for some hit-testing APIs but does not make it pass mouse
input through to whatever window is below it.

For that to work on modern Windows, the window needs to be both layered
and extended-window-style-transparent.

Additional logic changes to ensure mouse input passthrough, framebuffer
transparency and window opacity are mindful of one another when
modifying WS_EX_LAYERED.

Related to #1568.

e81d381256 X11: Fix disabling of GLFW_MOUSE_PASSTHROUGH
The client clip region was left in place when mouse passthrough was
disabled, leading to missing mouse input if the window grew beyond it.

d285a9fdeb Add support for mouse input transparency
This adds the GLFW_MOUSE_PASSTHROUGH window hint and attribute for
controlling whether mouse input passes through the window to whatever
window is behind it.

4ae93e0547 X11: Remove non-UTF-8 fallback paths
It seems it has not been possible to compile GLFW on systems without the
UTF-8 extensions to Xlib since a0a5cc57df
was merged five months ago.  The UTF-8 extension functions were
introduced with XFree86 4.0.2 in December 2000 and are likely widely
available at this point.

This removes the locale-dependent fallback paths and uses the UTF-8
extension functions where available.

9a3664b4a9 X11: Fix detection of key events duplicated by XIM
Background: The IM will filter out key events, instead sending exact
duplicate events that are not filtered.  It does not send these for
every event, however, so the duplicate events cannot be relied on for
key input.  Instead we need to identify and discard them.  Since they
are identical, they have the same timestamp as the originals.

The previous duplicate event detection would consume unrelated key
events if the keys were pressed simultaneously, as it only tracked
a single timestamp.

This fixes that issue for any combination of keys, at the expense of
a 1 KB array per GLFW window.

This fix is a stopgap until explicit IME support is done.

Based on #1472 by @LucaRood.

Fixes #1112.
Fixes #1415.
Fixes #1616.
Fixes #1663.

f5f060e6bf Init hint documentation work
The documentation for window hints had several features that had not
been carried over to init hints.

This also removes listing glfwInitHint for each hint, which was an

399c2a1fad Clarify docs on default GL header inclusion
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.

9a87c2a4b4 Add feature available/implemented errors
This adds two new error codes: GLFW_FEATURE_UNAVAILABLE for when
a GLFW feature cannot be reasonably implemented on that platform, and
GLFW_FEATURE_UNIMPLEMENTED for when it can be but has not been yet.

This replaces the current situation where the Wayland code emitted
GLFW_PLATFORM_ERROR in both cases while the macOS code silently did
nothing.

If your application exits on any GLFW error, these error codes should at
least be easy to filter out from that behavior.

Ideally, GLFW_FEATURE_UNAVAILABLE should be rare and
GLFW_FEATURE_UNIMPLEMENTED should never be emitted at all.

Fixes #1692.

105cf32e0b Fix desktop GL header not always being suppressed
If an OpenGL ES header or the glcorearb header is included before the
GLFW header (with no options defined), the legacy OpenGL header will be
implicitly included and the compilation will fail.

This disables the default behavior if we detect any known OpenGL, OpenGL
ES or extension loader inclusion guard macro.

91eebe922d Use CALayer instead of NSView for EGLNativeWindowType
The only two EGL implementations on macOS are Swiftshader and ANGLE.
While Swiftshader supports both `NSView` and `CALayer` as
`EGLNativeWindowType`, ANGLE supports only `CALayer`. Furthermore
Swiftshader's OpenGL ES frontend is deprecated in favor of using ANGLE's
Vulkan backend on top of Swiftshader's Vulkan frontend.

This means that on macOS `EGLNativeWindowType` should be a `CALayer` for
compatibility with ANGLE.
