yes I misunderstood. renderPM produces pixmaps via a canvas renderer and 
those pixmaps can be used as Drawings which are already flowables. The 
standard renderPM canvas doesn't support the code from platypus 
paragraph, tables etc.

.
internally we have already done this without using special widgets. 
Renderers already support the idea of canvases. An extension allows us 
to support most of the features needed for paragraphs, tables etc etc. 
The real problem lies in the special nature of the PDF canvas. It's 
unlikely that anyone would want to have multi page bitmaps or 
annotations or bookmarks etc etc.
