popup menus with zero px height

[Christian Kristukat]

Microcal Origin opens a color chooser popup menus with 0px height. This 
is due to the items having 0 px height. The patch checks that case and 
adds a constant (12) to lpitem->rect.bottom. Using a constant is surely 
quite ugly but helps in that case. I'd really appreciate to see that 
patch accepted as it's the only really annoying thing when using that 
application.

Changelog:
     - check for 0px high MenuItems
