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.
If multiple nested widgets have drag sources on them, both using bubble
phase, we need to reliably pick the inner one. Both of them will try to
start dragging, and we need to make sure there are no situations where the
outer widget starts drag earlier and cancels the inner one.
Currently, this can easily happen via integer rounding: start and current
coordinates passed into gtk_drag_check_threshold() are initially doubles
(other than in GtkNotebook and GtkIconView), and are casted to ints. Then
those rounded values are used to calculate deltas to compare to the drag
threshold, losing quite a lot of precision along the way, and often
resulting in the outer widget getting larger deltas.
To avoid it, just don't round it. Introduce a variant of the function that
operates on doubles: gtk_drag_check_threshold_double() and use it instead
of the original everywhere.
In destruction paths of a focused entry, the IM context might first
end up detached from its widget, then destroyed. This currently prevents
the IM context from detaching itself from the GtkIMContextWaylandGlobal.
Make it do so when unsetting the client widget, so the IM context gets
properly unfocused before destruction.

In particular, it will NULL-ified the current global context if this is
the finalized one, avoiding dangling invalid pointers.
Would have been a cherry-pick from branch gtk-3-24 of commit
b592ded80a, but files moved.
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).

(cherry-picked from commit d7fb15c822)
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.

All built-in backend modules get a priority of 0 because they are the
default ones.
GtkIMContextSimple gets a priority of G_MININT because it's the fallback
one.
This mirrors the media modules code.
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
When generating introspection data, we instantiate types without
calling gtk_init, so make sure that extension points are registered
before the type is trying to implement them.
