rendering tracks: use surface instead of tracktype

This is not a technical, but a human problem which concerns tracks in the United States. One typical example can be found here in the Napa valley:

American mappers usually don't use the tracktype tag, but the surface tag in order to display the character of a track. It would be too complicated to ask each of them to use the tracktype tag, so it would be easier to display tracks according to their surface:

  • paved=grade1
  • gravel=grade2
  • dirt=grade3
  • earth=grade4
  • grass=grade5

If American mappers see that surface is used for rendering, they might be willing to be more precise with mapping tracks.

Other solutions don't seem to be appropriate:

  • writing a personal message to each American mapper is too exhausting
  • editing all tracks in the United States manually is a little bit too much work for me

It is easier to change a renderer that to teach some thousand American mappers to use a specific tag.

I think rendering it likes this would suggest that there exists a one-to-one correspondence between surface and track types, which is not the case. I therefore think we shouldn't render it like you proposed. If the Americans don't want to add tracktypes, no problem - we just use the standard rendering.
