This has been made to work similarly to X11, requests for the data device
contents are notified through GDK_SELECTION_REQUEST events, the data stored
in the GDK_SELECTION property as a reaction to that event is then stored
into the wayland selection implementation, and written to the fd when
requested/available.

This implementation makes the destination side of selections work
similarly to X11's, gdk_selection_convert() triggers data fetching,
which is notified through GDK_SELECTION_NOTIFY events on arrival,
the buffered data is then available through gdk_selection_property_get().

What was happening that the button press event that we use
to select a widget caused another clicked signal emission of
the inspect button, starting another pick action.
Both Owen Taylor and I, the originators of this code, allow the code
herein be relicensed to the LGPL, which is what GTK+ ships with. This
prevents GTK+ from being GPL-only.
Add yet another set of checks and radios assets used in selected
treeview cells and selected list-rows, the standard dark variant assets
work well in those cases so no need for special casing there.
Use the left border color for tree lines. This is similar to
our use of top border color for grid lines. As a side-effect,
tree lines now get recolored when they are in a selected row.

We need to be a little more forthcoming with showing and hiding
the separators - their visibility now depends on the the visibility
and pack type of the regular headerbar children. This was observed
in gnome-contacts, where headerbar buttons are shown and hidden.
We used to move help buttons to the secondary position regardless
how they were added to the action area. Keep doing that, to avoid
breaking existing dialogs that rely on this behavior.

The previous way to invalidate was meant to work on the overshoot window
so it wouldn't be as taxing. Since the overshoot window is gone, this
would invalidate way more than intended. So constrain invalidated areas
to the sides where overshoot is happenning at that moment.

Using `font: Bold` will override the font with whatever the system
resolves a `Bold` font name to, including the font's own default size.
We want the font weight to be bold, but we want the default font name
and size to come from the GtkSettings:font-name property, like we do for
the rest of the system.
