Hello all,

Does anyone know why it is that angles are expressed
in degrees, as opposed to radians, in Performer apps?

I'm sure there is a resonable explaination for this
design decision (performance, implementation?), but
it forces the user to convert degrees to radians and
visa versa when intercomunicating angular information
with non-Performer apps. This process of having to
re-express angular information is inelegant and
performance intensive. Is there a way to get Performer
to accept radians instead?

While I'm on this issue, why is it that colors are
sometimes expressed in the 0-255 range and other
times normalized from 0 to 1? The man pages are
not always explicit as to which range a particular
Performer color is to be expressed in either.
