I think we should stick to policy of having a NeXTstep look ... and use
NSInterfaceStyle where people want alternatives.  So a patch to support
an interface style which gives a stippled scroller background ought
to be admissable IMO.

The NeXTstep look _is_ stippled. :)

I'll take your word for it ... I no longer have a NeXTstep system
since the
hardware I used for it died.  It didn't *look* stippled to me as far
as I can
remember, but I had a lower quality display back then and it could
just have
looked like a solid grey because of that.

 It is definitly stippled. If magnify screenshot of the scrollbar(as
 well as NSSlider) you'll see that.

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 :-)

I'm not so sure.  For all I know, it could as well have been:

    0.5 setgray
    0 0  moveto 0 200 rlineto 16 0 rlineto 0 -200 rlineto closepath fill

It just  happen that on a  2bit depth screen,  the best way to  do 0.5
gray is to mix dark ).33) gray and light (0.66) gray pixels.

The definitive  answer to that  question would be  to look at  a color
display that I don't have.

I booted up my color NeXT and found out it was stippled also. The interesting thing is that NeXT does this using the setpattern PostScript operator (which basically tells the DPS engine how to draw a color.). That's much more complicated than our PostScript "engine" works. The closest equivalent I could think of is drawing an image, like Nicola suggested...
