[cairo] Showing my ignorance about text rendering again

[Dov Grobgeld]

Pango allows you to get one line at a time from a layout through the
PangoLayoutLine. There is also cairo support for rendering
PangoLayoutLine's. So if you know what line spacing you want, it should be
trivial to get the same linespacing through pango/cairo.

Regards,
Dov
