I have made a small change to the font metrics which seems to help with the KePub problem where the page break cuts off the top of the glyphs leaving them on the bottom of the previous page when the line spacing is very narrow.

This doesn't change the line spacing, it just shifts the glyphs downward on the line, so there is more space above and less below. After a little testing on my Glo it seems to avoid the cut-off problem, as long as the line spacing is not so narrow that the ascenders and decenders actually touch.

(Edit: If this change works for this font, then I think the same could work for any font with this problem.)

The only change from v1 is:

* Changed HHead ascent/descent offset to 120/120.
