I have just spent a better part of two hours chasing a really stupid
bug caused by mixing uints and sints. The code in question was
scaling a sint value using the get*Resolution() functions, doing sint
* uint / uint, which resulted in loss of the sign (I noted the same
type of code in the ftlu()).

I do not know if that is standard C behaviour or just MSVC quirk, but
please when mixing ints of different sing, cast explicitely
everything to sint.

Tomas
