Why can’t I use more than 12 tab stops in NSTextView (enclosed by a standard 
NSScrollView)?
I can use less, but I need significantly more.
Is it to do with the ruler?

NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc] init];
NSMutableArray* ma=[NSMutableArray array];
for (int t=0; t< some large number; t++) {
        [ma addObject:[[NSTextTab alloc] initWithType:NSLeftTabStopType 
location:t*28.0f]];
        }
[style setTabStops:ma];
[mas addAttribute:NSParagraphStyleAttributeName value:style 
range:{0,mas.length}];

This works up to 12. Above that, it sticks to 12.

Applying something similar directly to the NSTextView paragraph style has the 
same problem.

How does Xcode & Text Wrangler pull it off?

TIA
Mark
