Am I the only one who thinks users shouldn’t have to add transparent

height?! Working with text should not require such efforts…

Unfortunately, LilyPond's idea of stencils is not prepared for doing that automatically: a stencil is basically a drawing _expression_ + an X extent + an Y extent. The info on the lines of text that made this stencil, if it was made from text, is lost.

It'd be possible to add an option for making equal spacing between the baselines of footnote lines, but it'd be a crutch: it would handle footnotes extending on multiple lines poorly.

The real fix would be changing the Stencil class to include an additional data member that would be the extent from the baseline of the first line of text to the baseline of the last line of text. Expect a lot of work though: all stencil operations would have to be modified to account for it.
