allthough there isn't much enthusiasm found for pie menus amongst the core
Gtk+ developers, we are certainly interested in reasonable additions to
the Gdk/Gtk layers.
in general, addition of new functions should be discussed on
gtk-devel-list@redhat.com, for moderatedly sized functions, it is often
a good idea to also post the actuall implementation, so things can be
discussed in more detail there.

this should cover a new event mask as well.

warping the pointer is a) a seldomly used "feature" and b) often very
irritating to the user, which is pretty much why Gdk doesn't currently
contain this function.
however, i think that the X interface for warping a pointer is overly
complicated (or "featurefull") and if at all, we should only provide
something as simple as:

gdk_pointer_warp (gboolean relative_move, guint x, guint y);

thit will warp the pointer to a position either relative to the root window's
origin or relative to its current position.
if you want the pointer to end up at a specific position within a specific
window, that can easily be computed through gdk_window_get_origin () plus
the offset.

what is this function meant to do? if you simply want to move a toplevel
gtk widget, gtk_widget_set_uposition() might be what you are looking for.
