Hi there,

Here is a dumb question. I need to do a translation before drawing a gset.
 There are two ways to do it. I can use pfTranslate() on a precomputed vector,
or pfMultMatrix() on a precomputed matrix. That is,

        pfTranslate(vector);
        pfDrawGSet(gset);

or

        pfMultMatrix(matrix);
        pfDrawGSet(gset);

I need to do this repeatedly over a large group of gsets per frame. Which one
is more efficient?

Thanks.

Gan
