Thomas, I like your proposition mainly because this would allow an 
easier maintenance/upgrade of the different renderers by removing 
duplicated code.
Looking into how this would  fit with existing swf, pdf, svg outputs, 
there are a couple of points that I am not sure how they would work:

  simple case is for example swf and pdf drivers use the GD driver to 
draw the rasters into a temporary image and integrate them in their 
"document". Would that be possible in this architecture? Mainly I think 
would the different renderers be able to redefine "high level" functions 
such ad DrawRasterLayer ?
I have started taking notes on how the different interface functions 
proposed would fit with the swf, pdf and svg and I am willing to put 
some time toward this if we generally agree to go forward with the 
proposition.
  Thanks for taking the time to draft this.

Best Regards,
