There are landuse=grass that used to render, but no longer do.
There's also a highway=footway area=yes multipolygon with the same issue, that I'd probably retag, but have left because it's also not rendering.
Cross-referencing #151 for place_of_worship non-building rendering.
I think the current color of place_of_worship is much to dark, when not applied to buildings.
Some mentioned issues are covered rather by "place of worship rendered like a building #151".
To allow displaying both place_of_worship and landuse it would be necessary to introduce transparency what gives really bad results (sooner or later) or change it from solid color into some kind of pattern (I have no good idea for any).
PoW no longer looks like a building. Is it still a problem?
Fixed - rendering order is now suitable.
