Overlays don't know about newlines.

We're using a multiline overlay: it both spans several lines, and its `before-string' property contains a multiline string when it's "on".

I suppose the overlay starts at the
beginning of some line after text T and has as many characters as there
are in the text with height O.  If you want to cover any text with the
overlay do that.

Sorry, I don't understand.

IIUC you neither need pixels nor lines in the end result.  You just want
to know whether a given overlay fits into a given window at a given

We don't have the overlay at that point in time yet: when it's created, it's constructed using the underlying buffer text, too.

Being able to just show a rectangle would require some dedicated API, like Eli mentioned.
