We can't use gtk_widget_get_allocation for either non-anchored widgets
(which happens with the child widget when the expander is unexpanded)
nor toplevel windows since that will include the window decorations.

Fixes #70 in gtk4

Instead of tracking whether the click happened inside the title widget
ourselves, just attach the gesture to the title widget.

Since this is a GtkContainer, forall will be used to destroy all the
widgets.

We free the allocated data later using g_free, so don't use GSlice when
allocating it.

Use the child widget list of the overlay, not the passed child.

We are creating these using g_object_new, so the _new function is never
called, resulting in a NULL mb_charset. Fix this by moving the
initialisation into the _init function.

gtkimcontextxim: fix gtk_im_context_xim_set_client_widget not handling widget=NULL

See merge request GNOME/gtk!46

Measure the text here directly and check if the created node bounds will
be clipped away before even creating the text node.

An alternative GskTextNode constructor that does no text measuring. That
way, we can measure the text before and check if the node will be
outside of the current clip anyway.

Both main child and all others are in the same coordinate space, so no
need to add the parent position here.

The GtkBin size_allocate implementation will allocate a size to the main
child, which GtkOverlay already does.

This was just testing that text nodes do alpha correctly, but the test
even breaks if the default font is different from the one that was used
to create the reference image, so drop it for now.

use an early return for an already existing layout.

gtk_im_context_set_client_widget() allows passing NULL as widget to signal that
the widget no longer exists. The xim implementation didn't handle that
case which led to the test suite on gitlab-ci failing.

(cherry picked from commit 3059df0d)

The CSS color spec version 4 introduces this, support has hit Safari,
Chrome and Firefox, so this looks like a feature that's here to stay.
