Insets are handled inconsistently at present, since menus use them to
offset the label text, whereas textlines don't. This is done because
menus need the margin to be visible when opened. However this causes an
alignment issue when menus and textlines appear in the same cedit.
Remove the offsets from menus and compensate by adjusting the bounding
boxes used for highlighting and the opened menu.
Line up menu items and textlines vertically and add a style option for
textlines to control how much padding is added.
Add a test to check the positions of objects in a cedit, since this is
more direct than the rendering tests. Add style information so that the
impact can be seen.
