I just want to point out SVG Tiny 1.2's buffered-rendering property, 
which had the same intent, but with a coarser set of values:

   http://www.w3.org/TR/SVGTiny12/painting.html#BufferedRenderingProperty

Presto implemented this, at least for SVG content, though with Opera's 
move to Blink I am not sure whether this property has any remaining 
desktop implementations.  The property has been ported over to SVG 2 
(still a Working Draft), though:

This isn't to say that we should prefer buffered-rendering, just that we 
should make sure there is only one property for this hint.
