  <p>(Benja:) Aaah, now we get to the real discussion! Yes, that's exactly what
              I mean. Now if you can give me a single good case where this is
              inconvenient and your system is more convenient, you've gone a 
long
!             way in convincing me of it. <tt>;-)</tt>

! <p>(Tjl:) Easy. &nbsp;Imagine a skewed, perspective coordinate system (i.e.
! using the homogeneous coordinate transformations of OpenGL). Now imagine
! e.g. putting an image behind a viewport transformed like that it so that
! you *don't* want to transform that image. Finding the inverse transformation
! there is not trivial and requires inverting a 4x4 matrix. It <b>can</b> be 
done but it's nasty. &nbsp; I can well imagine wanting to do this. Even with 
just rotations there's too much to worry about.<br>
