Personally, I think that all display objects should deal in points as the
default coordinate system. Of course, that would partially eliminate things
like the use of bitmaps for UI elements and icons. e.g. I might want a button
that's 0.2 inches tall (14.4 points) and 0.75 inches (54 points) wide, because
that's how big its label is. There are other problems of course (how thick is
that line? How do you make a grid look right if the scaling isn't quite
even?).

If the GNUstep developers want a vector-based display system like NeXTstep
mostly was, or like OS X apparently is, some kind of absolute coordinate
system like points would be rather nice. However, without DPS, X doesn't like
that very much.
