If you look at the code for a single glyph,
`ft_glyphslot_grid_fit_metrics' in `ftobjs.c', you can see that we
indeed add ceiled and floored values. However, for the global size
metrics (in function `ft_recompute_scaled_metrics'), we don't do
that...
On the other hand, David is right: For some non-TrueType font formats,
`height' is not always `ascender - descender' (cf. cffobjs.c:752, for
example).
So probably the current behaviour is the right one, or we indeed add
the guard David has suggested. Tricky, tricky.
