Minimal Smart Render

this is almost the bare minimum code to use with smart render.

it actually doesn't use any of the smart render.

it would just allow you to render 16 and 32 bit, with the minimal hassle.

just don't froget to set the correct flags in the global setup.

p.s.

this code might (and probably does) contain errors.

but with a few tweaks you should be up and running in no time.
