That's true, but I'd set it the pageInc to 10 not 11...

Well, I get slightly different results, but the issue is the same. After
checking again here's how I got the 0-100 with the proper tick marks:
startValue = 0
endValue = 100
pageInc = 9
lineInc = 1
But you're right that clicking on the scrollbar jumps every 9 - and if you
want to jump every 10, you need to set the pageInc to 11, which screws
everything up.
Sounds like a bug to me...
