Add support for patterns
Draw distance markers
Changing example, DistanceMarker groups, show/don't show types
Fix bounds (for distance markers), update examples
Add displacement function

‘random’ (not really) displacement which is always the same for the
same input.
Change visible and hidden defaults and marking tees

Visible and hidden types are now null by default. So now, if you set
empty array to visibleTypes it will not draw anything.

I have also fixed marking tees, as it was drawing the mark, even though
that type was not visible.
Handle distance markers near top/bottom
Show 2 distance markers in the same row
