Fixes terminal emulator misbehaviour as outlined in https://gitlab.gnome.org/GNOME/gtk/issues/1316, which was introduced in 49b17e6c. The original commit cleared preedit text by setting it to an empty string, which still counted as existing preedit. The fix sets preedit string to null, which is correctly understood as not present.
There may be situations where this might get called while the
currently focused context just went away (eg. after setting the
text widget unsensitive).
Closes: #1317
This fixes a potential leak of a PangoAttrList that is set when chaining
up to the parent get_preedit_string(). We check to see if the attr list
was created and reuse it instead of leaking the previous value.
If the parent get_preedit_string implementation returns a nonnull
zero-length string, then we ignore it, which is almost fine. We have to
free it, though.
Fixes#1174
Fixes two things: 1) As GTK+ can be coerced into using the wayland IM
module despite the compositor not implementing the interface, all paths
not checking for global state before sending requests are prone to
crashes, this one fell hit this pitfall.
And 2) ensures the tap gesture only triggers TOGGLE_INPUT_PANEL if the
widget IM is focused. This is a possibility on eg. WebKit pages, where
its IM is only focused as long as a form element in the page is focused.
Tapping elsewhere shouldn't toggle the OSK.

This IM context implementation goes through the gtk-text-input protocol,
leaving up to the compositor the actual interaction with IM engines. If
the protocol is not offered by the compositor, GTK+ will fallback to the
IMs as specified through GtkSettings.
On Windows, when IME is used, each keystroke results in the
WM_IME_COMPOSITION event being sent first. This means that in our case
when one decides on to accept the input that is in the preedit buffer,
we first get from Windows the WM_IME_COMPOSITION event
(where we emit the commit signal), followed by the WM_IME_ENDCOMPOSITION
event (where we emit the pair of preedit-changed and preedit-end
signals).
Since commit f11f989 (GtkEntry: Remove recompute idle), we do the input
recomputation directly, this will cause a pair of "Pango-WARNING:
Assertion failed: (index >= 0 && index <= layout->length)" being shown,
as gtkentry.c's priv->preedit_length and priv->preedit_cursor was unable
to be reset to 0 in time as a result of the recomputation triggered by
the commit being done before the reset of priv->preedit_length and
priv->preedit_cursor (which are no longer valid as we essentially say
that we are done with the preedit buffer).
As we could only acquire the final string that was entered in this
preedit session when we handle the WM_IME_COMPOSITION event, fix this by
saving up the final string we acquire from Windows IME in UTF-8 when we
handle the WM_IME_COMPOSITION event from Windows, and emit the commit
signal with that string after we emit the preedit-changed and
preedit-end signals when we handle the WM_IME_ENDCOMPOSITION event from
Windows, which comes afterwards.
Also fix the formatting of the code around the parts of the files that
was changed.

Replace checking if the NSView is really a GdkWindow, which will crash
in the likely event it's not a GObject, with ensuring that the parent
GdkWindow is really a GdkWindowQuartz.
This was added a few years ago, as a way to have _no_ im context
at all. But it didn't actually work. Make it work, and streamline
the handling of none by moving it all to gtkimmodule.c.
As part of this, add context to the translated names of all
im modules we ship.
g_utf8_get_char_validated() may return -1 or -2
return type is gunichar(guint32)
Therefore such checks like 'gunichar < 0' or 'gunichar > 0'
are always 'false' or 'true'(except when gunichar == 0).

We add a custom im module for broadway that calls some broadway
specific APIs to show/hide the keyboard on focus in/out. We then forward this
to the browser, and on the ipad we focus an input field to activate
the keyboard.
Commits the pre-edit string on receipt of focus_out and reset
commands.
Patch refinements by Cody Russell <bratsche@gnome.org> and
Ek Kato <ek.kato@gmail.com>
Replace the deprecated API calls with the updated APIs, and fix the build
of modules/input/gtkimcontextime.c, as we really needed
gdk/gdkkeysyms-compat.h (gdk/gdkkeysyms.h was already included)

The IME input method has been both ignoring keypresses of
non-spacing characters (ditching these as non displayable),
and not letting IME do anything about those.
Even though, the sparse documentation on IMM/IME seems to
hint that applications can't pipe non-spacing characters to
the input method manager, and experimentation shown that
those characters are indeed handled differently than how
it'd be expected.
Then, add basic handling of dead keys on the IME input method
itself , as it's not mutually exclusive with regular keymaps
with dead keys.

When an application translates a key event and drop its native event
before passing to imquartz, it can't recognize the NSEvent. On this
case imquartz doesn't emit any signals such as "commit" signal so
that the application doesn't insert any text. To avoid no response,
at least imquartz should fallback to slave GtkIMContextSimple.

In gtkimcontextime.c, use gdk_win32_window_get_impl_hwnd() to get to
the impl's existing native window instead of GDK_WINDOW_HWND() which
implicitly ensures a native window for the widget itself. This seems
to work around whatever GDK problem with native subwindows and fixes
the bug.
This is based on Michael Natterer's fix for gtk-2-24.
GDK_WINDOW_XID() has the side-effect of turning a window native;
this in turn can have unexpected effects such as black backgrounds.
Avoid this by using the XID of the toplevel.

Be a bit more careful in get_pango_attr_list() and
get_utf8_preedit_string() to ensure that the client_window is properly
created before proceeding, to avoid access violation/segfault crashes on
Windows with IME installed, especially when running the pickers demo.

These are just wrappers for the functions, and we want to
deprecate them. Stopping to use them internally is a good
first step. Also define GTK_COMPILATION so we can keep using
gdk_threads_enter/leave without causing deprecation warnings.
