Processing 1.0 How to define CUSTOM paper size?

Question

Hi all,
I'm working in processing and I'm looking for a way to define my own paper size.
This is the most "cleanest" version of the script.
In fact this part is as good as the exact script from seltar
So the main focus right now would be the line between the
four backslash lines.
