My another guess is that FontForge has now re-computed the
ascender/descender of the font based on the highest/lowest glyphs.
(Is that right?)

In fact, I had done some experimental fonts in my local copy after the
change in FontForge had been noticed. They worked well with GTK+ widgets.
But as I said, I was not sure about other apps, esp. Mozilla, where
clipping were occasionally found when used in HTML forms. So, they were
just dismissed, letting Loma be the only test alone so far.

Seeing comments in this thread, I may revoke the proposal to scale up
the fonts again.
