First, thanks for your great work in this field of high quality computer
graphics.

I tried the new pre release of epix2 but with no success. The compiler
complain not knowing about the vector class in the point class:

After looking into Point.h the error is comprehensible. There is a
forward declaration of the Vetcor class, but no include statment. In
Vector.h the Point class is used also, which leads in a recursion. I
don't know why this compiles at your side. Maybe I miss something.
