render footways, steps and paths from z14

[matkoniecz]

Rendering from z13 resulted in ugly clutter in fully mapped areas. Rendering of cycleways and bridleways is unchanged, as density of these ways is lower and there is almost no danger of messy clutter.

Many fully mapped areas result at z13 result in terrible mess due to displaying footways, paths and steps. Examples include Cambridge ( http://www.openstreetmap.org/#map=13/52.2173/0.1468 ) Berlin ( http://www.openstreetmap.org/#map=13/52.5091/13.4464 ), Moscow ( http://www.openstreetmap.org/#map=13/55.7676/37.6213 ), Kraków ( http://www.openstreetmap.org/#map=13/50.0730/19.9556 ), Paris ( http://www.openstreetmap.org/#map=13/48.8544/2.3571 ).

I am aware that this will make map worse in remote areas and places that have with less important paths and footways unmapped, but overall effect IMHO will be clearly positive.

(fully mapped = further mapping of current state will not change what is rendered by default style)

Example of change, Cambridge currently at z13:

I very much agree with this problem. However, I'm not sure if dropping footway rendering at z13 is the best solution. I also considered doing this, but even though I'd rather see the clutter of footways gone, I think it really introduces too much problems in remote areas. I am currently working on an alternative PR that keeps the footways at z13, but makes them much less visible.

I'd propose not to merge this at least until I have submitted my PR, so we can compare both solutions.

I also would be happier with something that looks acceptable at z13 and displays footways. Lets hope that your idea will work.

and it is my proposal how to fix #211 @math1985 wants to solve this by implementing #243

And Kraków.

Closed this awaiting my own PR.
