OK, now I see this:
```
PangoRectangle logical_rect;
PangoRectangle ink_rect;
pango_glyph_string_extents (pgs, pa->font, &ink_rect, &logical_rect);
PangoFcFont *fcfont = PANGO_FC_FONT (pa->font);
FTFace_accessor ftface (fcfont);
Box string_extent (
Interval (PANGO_LBEARING (logical_rect), PANGO_RBEARING (logical_rect)),
Interval (-PANGO_DESCENT (ink_rect), PANGO_ASCENT (ink_rect)));
```
Why are we using the `ink_rect` for Y extents but `logical_rect` for X extents?
