[Mapcss] MapCSS 0.2 finalization and cleanup

Hi.
I'm not inside MapCSS-Developing currently, but what do you all think 
about the idea of implementing a "mapcss test center".
It's a idea that came to my mind while reading the last messages on the 
list, so probably it's a bad one, but who knows...

I guess, all mapcss implementations should be able to take
1) a mapcss file or string
2) map data (not sure, if here osm.xml is or easily could be a common 
base format)
and produce an image out of that.

What about implementing this into e.g. a java toolkit (java, because 
it's running on any major OS usually), that enables the user to
- write a mapcss-style
- get rendering results of all registered renderers

This could be used
1) to check rendering results
2) to compare renderings and identify compatibility problems (between 
implementations and compared to the "standard")
3) as a design tool for style designers, including mapcss validation, 
probably giving hints or helping with "shortcomings" like the idea 
proposed by Thomas about nesting rules - as the tool could give an 
option for "make more specialized rule".

Just an idea - even if I don't have time to work on it.

regards
Peter
