good :) Now, I'm relieved.

that's right in principle.

you shouldn't. 

Effect rendering can be (and should be!) savely ported to C++, no
problem. (It's part of the render engine, isn't it?)

Please replace init -> C++ constructor, destruct -> virtual
~destructor() and add a proper factory class.

> a) We pass only the whole render structure, so yes

ok.

> b) Render engine only reads DNA (like movie path), doesn't alter it

good.

> c) Guarded Alloc has a nice macro for c++ classes

there should be an Allocator class, I wrote ages ago, yupe! :)

Peter
