	This is not 100% true anymore.  If your BILD object doesn't have any  
".color" directives in it, then the resulting object will be shown  
using the model-level color attribute, which can be changed in all the  
normal ways you can change model-level colors.  It may be true that  
parts of the model created before the first ".color" directive will  
use the model-level color (I'd have to find/read code I didn't write  
to verify that -- ugh!).
