Form the above I think you just need the ability to add drawn material of your 
own in a flowing document.

A simple way to accomplish that would be to define a Flowable subclass that 
allows you to do whatever you want to a page with canvas commands, but uses the 
Flowable api. In the code below that's what the DrawingStuff class does.
