Two brushes defined in HUDIcon-Ship.brushes cut off the images in Ascendancy_Ship_Main_Icons.tga.
MAINVIEWICON_SMUGGLER (used in NewRep_YT1300.entity) and MAINVIEWICON_SHREE (used in Ssi_Shree.entity).
The pixelBox dimensions are correct, but the text at the bottom of these images go outside of the standard 50 pixel height. The solution would probably be to adjust the images themselves and raise the text a few pixels.
MAINVIEWICON_ASDONI_FRIGATE (EotH_Asdoni.entity) and MAINVIEWICON_PELTAST (EotH_Peltast.entity) aren't clipped, but they are right on the edge.
