Hello!

I would like to color the timeline in 3 colors. 

lets say from 1 of  may till 1 of june the timeline will be red.

from 1 of june till 1 of july the timeline will be green

and from 1 of july till 1 of august will be yellow.

I could achieve something but its not what we need. because if I zoom in then the line of timeline always stays the same, but by logic of zoombar it also must be scaled or not shown part of it.
Only labels are redrawn on the timeline after zooming. 

So the question is : if its possible to achieve that. 

And the way how it colors now defines on runtime, so nothing is available, and we cannot just hardcode some style.

Thanks!
