Not all implementations of pie menus are worthy of enthusiasm.  Have
they seen Daniel Skarda's implementation, linked off of his home page
at http://atrey.karlin.mff.cuni.cz/~0rfelyus/ ?  He did a very good
job with his implementation.

I can easily imagine a configuration flag which turns popup menus into
pie menus.  They look and work better if the programmer has a way to
hint which compass direction the menu item should appear at (ignored
if the menu is linear).

Gratuitious warps definitely *are* annoying.  Pie menus have to warp a
little when needed to move the pointer away from the edge.  The menu
selection process needs space for the pointer to move in all
directions for all but two-item menus.

That would be sufficient.  Should I recode gdk_window_pointer_warp to
work as described above?

It was intended to allow a negative x and y to work, however, it's
never called with a negative x or y, so it's not needed.
