realwidth and priority in elemstyle.mapcss

[Klumbumbus]

In ​elemstyle.mapcss there are alot of realwidth=* and priority=*
Are these left from old elemstyle.xml? Do we need these in elemstyle.mapcss? Both are not documented on Help/Styles/MapCSSImplementation

priority=* was important for the z-index order in the XML style. I kept it in for reference, but may be cleaned up soon.

realwidth=* is related to an undocumented feature, which fixes the width of the lines in meter (so it gets bigger if you zoom in). I would like to get rid of this, but was waiting if anyone is complaining (doesn't currently work with MapCSS, but wouldn't be too hard to implement).

Actually, I do not use realwidth ATM but only because the "lane attribute" style (turn:lanes) does already do the job.

The hidden option was probably too well hidden for many user.

Shouldn't the goal be to display width=* ? But as mapnik does also not support it many users do not tag it.
