[Development] FP calculations and stability in Qt

I'd want to clear the context out of the way, so this is the bug that
got me thinking.
I appreciate that we want to keep external dependencies to a minimum, and
for a good reason, but can we talk about how feasible it is to pull
something (or parts of it) in Qt, even if only internally, to facilitate
stable fp calculation.
I've seen some complaints (on the forums mostly) about the stability of the
transformations Qt supplies, generally unfounded, however it'd be nice if
we can solve this with generality. I realize Qt is no math library and
support the idea to drop most of the global functions that dealt with math,
in the end they're already in the STL. However, as it is, we have some
linear algebra done (internally mostly), so I think it'd be nice to have
that done "correctly" for the user.
I'd appreciate feelings and opinions on the matter, as I'm but one person
and my view is rather limited.
