I don't think there's a line drawing function that supports this.  Basically,
you would have to add a parameter in fline for write mode, then change fline
to check the parameter and draw the pixel the right way.  This won't work if
fline just calls the ROM functions though.  You'll have to write your own line
drawing function.  (I have an algorithm for it if you're interested.)
