[Tagging] Feature Proposal - RFC - window:shape

[bkil]

Another aspect that you could think about is whether a window can be
opened or not (and which direction it opens). Something of interest is
whether a glass surface is a storefront (glass wall) or if it just a
smaller opening, but maybe you can already indicate this by other
keys.

By a metaverse explorer I wanted to share a possible future use, but
let's skip the topic of mapping for the rendered this week, okay?

For windows, if you KNOW they are double- or triple-glazed, add that fact as a datum, if not, omit it.  Generalize that to be "if you know it, tag it, if you don't, don't."
