  Plans are the easy part. :-) At this time I'm, not entirely sure 
whether an SVG rendering model for Gnash is a good or bad idea. As Gnash 
currently supports the XBox and OpenGL renders, it might be good to have 
another one. I think adding a Cairo renderer would be more useful in the 
immediate future though.

  This must get interesting when displaying fonts... I don't know much 
about SVG, but I'd think it would be useful to have Gnash be able to 
play a movie with an external or embedded SVG image, like it currently 
handles jpegs or pngs.

  Gnash & GameSWF are using a mix of custom rendering code, but mostly 
the rendering is handed off to OpenGL. You can look at the rendering 
code in the backend directory.
