Fine tune spacing between minor ticks in rulers.

Browse Source 
The main point of this is not to ask for overcrowded rulers.

We already handle overcrowded rulers well, by not showing the minor ticks.
This change means that we are more likely to ask for a spacing that works.
In turn that means that we are less likely to have anomalies where numbers disappear due to overcrowding and reappear again as you resize the ruler.
