support for roof:ridge and roof:edge

[Sinuhe20]

Hello,

I would like to have a support for roof:ridge and roof:edge, like OSM2World has, see https://wiki.openstreetmap.org/wiki/Relation:building .

.Actually roofs tagged in this way are not rendered correctly:

Kendzi3D:

OSM2World (how it should look):

You can also see that benches have wrong directions and trees not the correct height in Kendzi3D.

Best regards

For wrong bench direction rendering see #98.
