haiku-beta6/src/kits/interface/MenuItem.cpp
T
Stephan Aßmus 306e92084c * small cleanup of Draw (less usage of ui_color() which currently 
takes a trip to the server!)
* changed look of mark and submenu symbol to better fit the rest
  of the already changed controls
* the actual background color is passed to DrawMarkSymbol() and
  DrawSubmenuSymbol()
