After writing many OI programs, I have not found a case where I had to
put something like
	if (I'm in motif)
		do brain-dead things
	else if I'm in Openlook
		do other brain-dead things
in any of the code that I have written.  Modulo funky "look", the
Openlook and Motif style guides are not really that different.  There
are many "feel" issues that the toolkit takes care of and that I as a
toolkit user need never worry about.  It may take some careful
planning, but it usually isn't that big an issue.

In OI there are many different types of scrolled objects.  The
application writer can either tell the scolled object to have scroll
bars in a specific place (like on the left and to) or tell it to user
a vertical scroll bar and the toolkit will place it based on what GUI
the user selected.
