How do pfDCS calls affect each other? For example:

pfDCS *dcs;

pfDCSMat (dcs, some_matrix);
pfDCSRot (dcs, h, p, r);

If I have some uniform transformation to do (represented
as some_matrix) and then want to apply some rotation or
translation afterwards, does the rotation call overwrite
any part of the matrix?
How about the reverse case?

pfDCSRot (dcs, h, p, r);
pfDCSMat (dcs, some_matrix);

I'm getting some strange results in porting some gl
code to Performer. They use multmatrix calls either
preceded or followed by rot calls. I'm not sure if
my method is working.
Thanks.

Rudy
