it ignores the "over" line modifier. This is because of l. 144 in
ElemStyles.java:
over.remove(linestring);
(Where linestring is the condition key for the line style.)
Is there a reason for this behaviour or can we remove the line?
Yes, there is. Overlays are used to combine different styles. When there
is a basic style of this type, then this should be used instead.
Example:
- When I have a street including tram, then I draw street with Tram as
overlay.
- When I have only a tram, then I draw a tram directly.
Allowing overlays overlaying the same basic type would make things much
harder to control.
Overlays aren't meant to improve drawing style of single elements. This
would be too costly during drawing.
