Otherwise, it is pretty hard to keep track of what
classes are missing from the list. As a consequence,
several of the existing classes were missing. Add those
at the same time.
Event controllers now auto-attach, and the GtkCapturePhase only determines
when are events dispatched, but all controllers are managed by the widget wrt
grabs.
All callers have been updated.
And handle the fact that drawing bounds are now handled by this API and
the corresponding gtk_widget_get_clip().
Also add _gtk_widget_supports_clip() function to check if a widget has
been ported to the new world.
All "exclusive" gestures listen for either pointer events, or
"pointer emulating" touch events, so only a single sequence at
a time can make these run.
The propagation phase property/methods in GtkEventController are gone,
This is now set directly on the GtkWidget add/remove controller API,
which has been made private.
The only public bit now are the new functions gtk_gesture_attach() and
gtk_gesture_detach() that will use the private API underneath.
All callers have been updated.
Add api to allow explicitly setting a GtkPopover instead of
a GtkMenu as the popup of a GtkMenuButton. Also, add api to
instruct the menu button to construct a popover when given
a menu model.
We set the style class "menu-button" on the button only when
it pops up a menu, to allow different treatment for the active
state of the button in the two cases.

This adds a new function, gtk_popover_new_from_model, which creates
a popover and populates it with suitable content according to the
menu model. The current implementation uses GtkModelButton for the
individual items, and a GtkStack for submenus.

This property is TRUE by default, when a popover is modal, it
will automatically set a GTK+ grab on the popover, and grab
the keyboard focus into the popover.
