[dmpr0]

Description

We can add custom shields for route without symbol:

• White background or equal to route color
• Symbol equal to route type

Examples:

• MTB – https://www.openstreetmap.org/relation/1777778
• Hiking – https://www.openstreetmap.org/relation/4483721, no icon and color
• • With colour – https://www.openstreetmap.org/relation/12540906

ToDo

• Prepare icons for all supported route types:
• • hiking
• • horse
• • fitness_trail
• • bicycle
• • mtb
• • running
