I beleive it is ok to use negative rotations, as the Hello sample use a
rotation of MakeWWFixed(-15).
Plus I tried keeping all rotations positive (360-degree), but the same error
occurs.

As a side note... You can use MakeWWFixed with the following values: 10, -10,
10.5.
But it does not work with a value of -10.5. It calculates a wrong value.
For this you have to MakeWWFIxed(0) - MakeWWFixed(10.5) or
MakeWWFixed(10.5) * (-1). (Its ok to directly multiply a WWFixedAsDWord by an
INT value, but you have to use GrMulWWFixed when multiplying 2
WWFixedASDWord)
