Tweak the preedit text we get from IBus (via the compositor) to
match what GtkIMContextSimple produces for Compose sequences now.
This provides a unified experience.
In the paths where len > MAX_LEN and cursor/anchor are separated by
at least MAX_LEN from text edges, we were clamping the right end of
the surrounding string at MAX_LEN. Oops.
This end anchor may go as far as the string length, although just
up to len - MAX_LEN in real terms (due to the condition above that
caches cursor/anchor positions being near enough the text end).
Closes: https://gitlab.gnome.org/GNOME/gtk/-/issues/2565
To find the middle of the string, we should check both cursor/anchor.
This is actually a backport of commit 8fc360dac5e4 in master.

GtkIMContext get_preedit_string should return cursor position counted
in characters, but cursor_begin here is counted in bytes. This add the
missing conversion.
Specifically it is avoided to be toggled if:
- Just received focus (in order to preserve OSK state across focus changes)
- Moving cursor around. Still allow some jitter as perfect accuracy is not
possible.

Before this patch, imwayland would assume that text-input enter and leave events follow the general (wl_keyboard) focus, and was unable to handle the situation where they would not be provided at the same time.
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.
