So if you want results with bad resolution for your panning, using tabulate=
d=20
values will work. But that will result in "jumps" in the panning. Better le=
t=20
the cpu calculate the sin/cos directly. And then realize that approximating=
=20
the sinus in that range by another, simpler function speeds up the process =
to=20
the point where its faster then looking up a value in a table...
If it was just about small angles less then say 3 degree, the best=20
approximation of sin(x) is x itself :-)

Have fun,
