Re: Progress of text system

It's late here, so this is just a quick response addressing a few of the
issues. I'll respond to the rest of it and explain (again) the reasons
for the design tomorrow.

I've brought back the implementation of
-rulerMarkersForTextView:paragraphStyle:ruler:. AFAICT, all methods that
were implemented are still implemented now. If there are any others I've
missed, please tell me and I'll bring them back too. There are still
things left to implement, though.

Color, both foreground and background, is implemented, and it works
here. (There seems to be a bug in rtf-parsing that interferes with
loading colors, though.)

Are you sure this is accurate? None of my testing has indicated that
-setLocation:forStartOfGlyphRange: is a bottleneck. On the other hand,
I've never been able to profile GNUstep programs properly; I always get
completely bogus values. Are there any known pitfalls when profiling
GNUstep programs?
