GtkTextView::measure should include the height of the text-layout in its
minimum and natural heights. This fixes scrolling when a text-view has a
scrolled-window ancestor that is not its immediate parent.
Don't use the current layout size as minimum size anymore, that doesn't
make sense. Also move the code from size_request() from gtk2 into the
now current measure() function.
Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.
The main GDK thread lock is not portable and deprecated.
The only reason why gdk_threads_add_timeout() and
gdk_threads_add_timeout_full() exist is to allow invoking a callback
with the GDK lock held, in case 3rd party libraries still use the
deprecated gdk_threads_enter()/gdk_threads_leave() API.
Since we're removing the GDK lock, and we're releasing a new major API,
such code cannot exist any more; this means we can use the GLib API for
installing timeout callbacks.

This is in preparation of using input streams to show that these
coordinates aren't needed most of the time and can otherwise be saved
during GtkWidget::drag-drop.
Instead of using GtkClipboard and handling everything ourselves, we now
put GtkTextBuffer into the GdkClipboard and register (de)serializers for
text/plain.
It's unused. Plain text is not using that framework, neither is
in-process same-display transmission.
So it was only useful for sharing text with custom tags across
applications, and nobody is doing that.
Similar to GtkEntry, add an "Insert Emoji" context
menu item, and add the same keybindings. We don't
add the icon here, since it is not clear where it
would go.

This is not used by anything yet, but add it now, so people looking at
this new code can make sense of it.
Plus, the documentation mentions it, so better have the docs make sense.
It will be used once we add support for conversions to GDK and allow
doing cipboard/dnd by GValue.
Make sure the API reflects the idea that GdkContentFormats is a set
containing mime types. In particular, treat the object itself as a
plural - it's named content format`S' after all - and therefor use
the correct verb form.
Also make GdkContentFormats keep an array instead of a list, now that
it's immutable.
Instead of allowing people to pass a uint user-data, insist on them
comparing mime types.
The user data was a uint instead of a pointer anyway, so uniqueness
could not be guaranteed and it caused more issues than it was worth.
And that's ignoring the fact that it basically wasn't used.
Instead, add a function gtk_image_set_icon_size() for the cases where
overriding the icon size is necessary.
Treat icon sizes the same way as pixel sizes, too. So gtk_image_clear()
no longer unsets the icon size.
GtkSourceView is not using it, so it's unneeded. And it's certainly
diving deep into event internals of GtkTextView which hinders a proper
gesturization.
The selection bubble is not part of the text windows, so hiding it
during scroll should not be done in the text window code.
Also remove an unused variable that was only set in that code but never
read.
A sideeffect is that we don't set the correct parent window on child
widgets anymore, but that is hopefully going to be fixed once we get rid
of child windows completely.
Change constructors to reflect that.
While doing so, also add a fallback argument to the cursor constructors,
so it is now possible to create cursors with fallback.
It was used to mark css properties that affect widgets with text, but it
caused unnecessary invalidations. E.g. 'color' was marked as
AFFECTS_TEXT but changing just the color of a label should not
automatically queue a resize, which is what the code in
gtk_widget_real_style_updated does.
Replace this flag with GTK_CSS_AFFECTS_TEXT_SIZE and
GTK_CSS_AFFECTS_TEXT_CLIP, which GtkWidget can use only if the widget
actually has text.
