Windows keymaps contain some bogus mappings, e.g. Ctrl+Backspace=Delete.
Previously, we correctly identified the key as Backspace, but the Ctrl
was still consumed, so the Ctrl+Backspace keybinding did not work.
gdk_win32_keymap_translate_keyboard_state erroneously used the active
group rather than the specified group, which caused shortcuts not to
work in Inkscape when using a Cyrillic layout.
This consolidates the check for the running CPU in one single location,
to make things a bit cleaner, as:
* We can make use of IsWow64Process2(), if available, to check both
whether we are running on an ARM64 CPU, and whether we are running as
a WOW64 process. This is also the function to use to properly check
whether we are running as a WOW64 process on ARM64 systems, as
IsWow64Process() does not work as we want on ARM64 systems.
* If we don't have IsWow64Process2() (which is absent from Windows prior
to Windows 10 1511, where ARM64 Windows is introduced), we can fall
back to IsWow64Process(), which will tell us whether we are running
as an WOW64 process (but clearly not on an ARM64 system).
Also clean up things a bit so that we can reduce reliance on global
variables.
The old code used repeated calls to `ToUnicodeEx` to populate
the translation table, which is slow and buggy. The new code
directly loads the layout driver DLLs from Windows.

MinGW-w64 CRT provides no 'hid.lib' file. Instead, it has 'libhid.a'
which can be linked with '-lhid' linker argument.
Also, we have to declare the '_LIBADD' variable and add 'LDADDS' to it,
or 'LDADDS' won't do anything for the build.
Note that gdk_monitor_get_geometry () returns DPI-scaled values,
while the screen offset should be unscaled, as scales are properties
of indivdual monitors.
An arithmetic operation involving a signed and an unsigned operand
of the same rank will have both operands converted to *unsigned*.
That's an issue if the signed operand actually has a negative value.
That was causing issues with the handling of monitor geometries that
had negative x / y positions.
...if GLES (libANGLE) support was enabled in the build. This way, we can
check whether the GL driver is capable enough to support the OpenGL
features that we use in GTK. If the driver is not capable enough, and
GLES support is enabled, we can try to create the GdkGLContext again as a
GLES context.
Group the WGL-specific code and GLES-specific code together, so that we
can reduce the number of #ifdef ... in the code, to make the code more
readable and easily maintained. This will pave the way to add a
fallback mode to use libANGLE (OpenGL/ES) in case the Desktop OpenGL
support is inadequte, if OpenGL/ES support is enabled in the build.
This is somewhat based on the updates that were done in GTK master, so
we are using one subclass for WGL-based GdkGLContexts, and another for
GLES-based GdkGLContexts.
Also remove the underscores in many of the functions in
gdkglcontext-win32.*.
Clean up the code a bit as a result.
Like the recent updates in GTK4, the HWND that we use to obtain the HDC
that we need for OpenGL/GLES operations should really be tied to
GdkWindow, not GdkDisplay, as that is where the Win32 HWND where we
originate from is located, so stop storing the GL HWND in
GdkWin32Display, but just grab them from the GdkWindow that is bound to
the GdkGLContext.
We are more conservative about freeing up GL resources in GTK3, so we
will continue to call ReleaseDC() as we did before.
It apparently worked by chance in the past, but now causes e.g.
alphanumeric characters to be interpreted as half-width katakana
when using the Japanese IME.
Some GL drivers such as Mesa-D3D12 do not allow one to call SetPixelFormat() on
a given HDC if one pixel format has been already set for it, so first check the
HDC with GetPixelFormat() to see whether a pixel format has already been set
with the HDC, and only attempt to acquire the pixel format if one has not been
set.
This will fix running with GL on Windows using the Mesa drivers.
We can just group the code for the desktop GL codepath and the EGL
codepath a bit so that we can just have a single location where we
return TRUE upon a successful setup of our WGL/EGL context, and avoid
the C4715 warning that is considered an error when building with
GLib-2.68.x or later using Visual Studio, when we are building without
EGL support.
Partially fixes issue #2191 regarding switching to another app while
hovering a stylus over a drawing tablet causes subsequent mouse
clicks in the app to be ignored. I was not able to reproduce the
other behavior described in #2191 concerning tiling a window.
Intel OpenGL drivers have an issue where the results of a series of
glBlitFramebuffer() can delay updating the display, when we use GDK_GL=always,
which is manifested when attempting to enter text in text boxes.
This attempts to work around this issue by requiring a glFlush() call and a
retry to the same glBlitFramebuffer() calls to avoid delays in keystrokes when
using GDK_GL=always and when not using libANGLE OpenGL/ES emulation, when an
Intel OpenGL driver is being used.
Special thanks to Lukas K. for the analysis and coming up with a workaround,
which this patch builds upon.
Fixes issue 3487
In gdkdevice-win32.c we are interested in knowing which window
receives mouse input at a specific location.
Only WindowFromPoint is the right API for the task, other API's
(such as (Real)ChildWindowFromPoint(Ex)) have shortcomings because
they are really designed for other purposes. For example, only
WindowFromPoint is able to look through transparent layered windows.
So even if we want to find a direct child we have to use
WindowFromPoint and then walk up the hierarchy.

Previously, a GDK application handled the Wintab cursors (stylus,
eraser, etc.) only during app initialization. If new cursors were
recognized by Wintab during app execution, the app would not know
about them.
This fix still handles Wintab cursors known during app initialization.
In addition, when Wintab recognizes new cursors and notifies the app
via a WT_CSRCHANGE message, the app handles the new cursors, creating
new Wintab device objects for them.
Closes#1549
