This is necessary to avoid unwanted drag cancel animations,
now that GtkNotebook is careful about cancelling a drag
when the dragged tab disappears unexpectedly.
When a tab is dropped, we have to remove it from the notebook to
insert it elsewhere. This is expected part of the tab dnd operation,
and we need to differentiate it from 'spontaneous' removals which
cause us to cancel the drag operation.
when the dragged tab is being removed during the drag operation,
we need to cancel the drag. To do so, we have to keep around
a reference to the drag context.
This should fix

Regions are done in a very non-css way. They don't fit the DOM in that
they don't integrate into the CSS tree and they have very weird matching
behavior in selectors.
So I'm deprecating them now. GtkNotebook and GtkTreeview will continue
to use them and as long as they do, we can't remove the code for it.
But once those are ported it might be safe to remove the code as it will
clean up lots of places in the code by quite a bit.
The extra condition here that caused the current child to
not redraw during reordering was introduced in f383e1f1
during the port to ::draw, but was not explained in the
commit message, and removing it has no obvious negative
effect.

Try to do a better job of keeping example content
from being too wide. It is often rendered as <pre>
text so the only time we can wrap it is in the source.
It is best to full break lines at all punctuation and
to try to keep the width under 70 chars or so.
Add a has-tab-gap style property to GtkNotebook so that we can
disable drawing the gap between tabs and the page in the Adwaita
theme without breaking existing themes.

And use the "header" style class to do that.
This allows themes to set e.g. the background of the tab header
differently.
Themes will need slight adjustment to make things appear
as before.

Attached widgets inherit from the style of the widget they are
attached to. This can sometimes have unintended consequences,
like a context menu in the main view of gedit inheriting the font
that is configured for documents, or the context menu of the preview
in the font chooser coming up with humongous font size.
To fix this problem, we introduce a context menu style class
and use it for all menus that are used like that. The theme
can then set a font for this style class.

When trying to drag, we currently the position of the first motion
event to determine where the drag came from. This might be alright
in the case of the old animation, but the data will be inaccurate
if the user has moved the pointer quite a bit since pressing the
cursor to start dragging. While we could monkey patch the GdkEvent
at the widget layer, this is unintuitive and strange.
Add a new API that takes a set of pointer coordinates describing
the origin of the drag. Additionally, adapt most widgets to use
it and use it with correct coordinates.
