Extend bus (psv) lane rendering support

[gaben]

"Lane and road attributes" mappaint style offers really good capability with turnlanes-tagging plugin. The only downside I came across, that it currently not supports all widely used bus (psv) lane tagging schemes.

For possible values see the wiki:
​https://wiki.openstreetmap.org/wiki/Bus_lanes

According wiki:/Styles/Lane_and_Road_Attributes it supports:

• ​bus:lanes: Dedicated bus lanes.
• ​psv:lanes: Dedicated PSV (public service vehicle) lanes.

Ah yes, thanks for the info. Then just the support needs to be extended :)

Please, describe what is missing with a small data example file if possible.

If you look at the wiki, you can see that there are 3 different tagging schemes. Namely:

• The busway=* scheme
• The lanes:psv=* scheme
• The bus:lanes=* scheme

Now, in my understanding only the last one is supported, the other two is not.

Three different tagging schemes for one situation is not that good.

• lanes:psv=* or even lanes:bus=* completely turns the:lanes-tagging around and only says how many psv-lanes there are but not where.
  • As the preset is about :lanes-tagging lanes:psv=* should not be supported as it would lead to a complete mixup and the scheme is not needed at all as it is covered by :lanes
• busway=* seems to be similar to cycleway=* with the same problems that the position of the lane is not clear.
  • The older scheme busway=* might be supported but, yet, again we have a better working scheme, so why support the other one.

Yes, I agree but this ticket is about mappaint not tagging.

• lanes:psv=* or even lanes:bus=* completely turns the:lanes-tagging around and only says how many psv-lanes there are but not where.
  • As the preset is about :lanes-tagging lanes:psv=* should not be supported as it would lead to a complete mixup and the scheme is not needed at all as it is covered by :lanes

Sounds good, but in this case, there is a huge difference between logical tagging (which the mappaint style aims at) and real tagging with documented wiki. These should be consolidated somehow to avoid confusion.
