Like I said earlier: I think it would be better to have the tooltip
text in a separate property, not as part of the 'display' property
spec.

Also, I don't see a need for recording the positions in the glyph_row
structure, because finding the glyph that corresponds to buffer/string
text with that special property is easy enough.
