14d22cb323 tooltip: Implement positioning using gdk_window_move_to_rect()
In order to make tooltip positioning portable, make use of the
move_to_rect API. Some semantical changes are made, as identical
semantics cannot be implemented using the move-to-rect API.

Primarily the implemented semantics are:

Position the tooltip in the center pixels slightly below (defaults to 4
units below) the tooltipped widget. This is always the case for keyboard
driven tooltips; the case where it tries to avoid the pointer cursor is
not implemented.

For pointer position triggered tooltips, implement the following
additional semantics:

Use the current cursor size to determine the padding used to enlarge the
anchor rectangle. This is to try to avoid the cursor overlapping the
tooltip.

If the anchor rectangle is too tall (meaning if we'd be constrained
and flip on the Y axis, it'd flip too far away from the originally
intended position), rely only on the pointer position to position the
tooltip. The approximate pointer cursor rectangle is used as a anchor
rectangle. Ideally we should use the actual pointer cursor rectangle
(image used as well as hotspot coordinate), but we don't have API to
get that information.

If the anchor rectangle isn't to tall, just make sure the tooltip isn't
too far away from the pointer position on the X axis.

0e0b45602a tooltipwindow: Use a builder UI file
It's not a hugely complicated file, but it's easier to deal with some of
the details of tooltip windows styling if we have a UI file to edit,
instead of source code.

534f537a3c Fix an oversight
We must set the construct-only "type" to GTK_WINDOW_POPUP, otherwise
this ends upo being a regular toplevel.

a846fd586d Add GtkTooltipWindow private sub-class
GtkTooltip does a lot of set up on the GtkWindow it uses internally. We
should move that code to a separate class to keep it contained.
