Currently, you can't - but all the infrastructure is in place
inside of IM to provide that in the future...

But does AW need to have all the features for parsing and
rasterizing it ITSELF - or is there a reason it can't simply ask IM to
rasterize it for it? It would seem to be "reinventing the wheel" to make
AW also have a full SVG parser and rasterize when we could just pass the
SVG (stored/handled by AW) to IM to get a bitmap for display.

Not currently, no :(.
However, what we COULD do is ask IM to convert SVG to MVG which is
a simple list of operations that could then be easily "thrown against" the
current graphics & printing systems. HOWEVER, by doing this you WILL lose
quality and completeness in the SVG output since none of the native graphic
subsystems completely support all of the "core" SVG features.
