[snip patch that adds attributes
 <image image-rendering='crisp-edges' style='image-rendering: pixelated' ...
]

Thanks.  That's a good start.

As tested here those attributes are indeed honored by firefox and chrome.
Mixed success on other svg handling programs.

Works:
   chrome
   firefox
   inkscape/inkview
   ImageMagick

Fails:
   konqueror
   LibreOffice / soffice
   gwenview
   gimp

Unknown (did not try):
   eog
   geeqie
