hap: is there any chance we can at some point do the 'halftone dots' thing in the svg as well? I think there's a way to do it in inkscape, but not sure how contrived it is...
I remember doing the texturing in my original dm53 svg (which had low-ish quality lcd blacks but high quality backgrounds thanks to your photographs). I doubt the current renderer can tackle them, but that just means the renderer has to be made better.
