Feature request: Tint barrier=wall with colour=*

[ivanbranco]

Since barrier=wall is a supported tag, could it be tinted with colour=* value? It could be extended to all supported values, I can think also of a monochromatic sculpture ecc.

There's also material=brick (etc) potentially available for texture+colouring

Same for chimneys, benchs, gates?
