... are always displayed with rounded corners, which looks just wrong
with menus for certain kinds of custom pop-up buttons and, most
importantly, NSStatusItems that pop up their menus themselves --
instead of using NSStatusItem's built-in menu functionality.
On the other hand, generic menu bar menus _are_ displayed with sharp
upper corners.
So I was wondering: Is anyone aware of a way to change those corners
for a NSMenu or its underlying Carbon menu?
