I think Adam was right in holding the patch until the issue was clear ...
but yes, looking at screenshots on the web, it seems that NeXTstep did
indeed used a stippled background for scrollers, so I'd say we want the
same by default :-)

However, I'd personally feel that the stippled background would be better
implemented by tiling a simple image (that is, drawing the image many
times, repeateadly, to cover the area), rather than by drawing a net of
dashed bezier paths.

It feels faster to me (but I've got no objective benchmarks, and I'm happy
to know that it's not that way) and it would have the important advantage
that by replacing the image with a different one, people should be able to
customize the scroller background more easily.
