I've separated the specific PDFRender functionality from the CTM class
and created a small utility class for the renderer to use.
This solves the problem I was having using the CTM and PDF classes
outside of the FOP context.

+ACo of the matrix will be divided by 1000 as FOP uses millipoints as it's default user space and PDF uses
