Ah, that makes sense then. I always think of pitch as up/down, like a flying a plane
Still leaves me with the problem of fonts incorrectly reporting their heights though, I haven't had a chance to look further into it yet.
The height of font in general is tricky bussines. You can ask for the height, but you cannot count on what you get. In fact, some glyphs even exceed character cell boundaries written in TTF metrics - this is by design.
Not ideal, but something we simply have to live with....
