TimeRulerItems Style

[Oscar Wahlen]

I have customized the TimeRulerItems using a custom Style Selector but now there is a 1 pixel margin after every n days (see attached screenshot). I can not figure out what is causing this behavior. I want to create equal width columns but the margin is causing each day to shift by 1 pixel. The blocks represent one appointment (e.g. a 7 day appointment is displayed as 7 blocks using a custom appointment brush). But as you can see they are not correctly aligned.
