I'm just learning to program in C on my Amiga.  I have set up a custom 
screen on which I have put a borderless backdrop window that is 
full-screen in size.  All I want to do is to change the background color 
of the window to black.  It is currently blue.  Try as I might, I can't 
figue out how to do this seemingly simple thing.  I've read all about 
the colormap and the SetRGB4() function and all of that, but I don't 
have a viewport defined.  How do I change the background color?
