I think this may be a regression -- I'm fairly sure that at one point we had added code to dither gradients to reduce the appearance of banding.
It seems I was thinking of this patch:
http://inkscape.svn.sourceforge.net/viewvc/inkscape/inkscape/trunk/src/libnr...
...which did help gradient rendering a little bit, but simply my using cleaner math rather than dithering.
Any remaining improvement is going to have to be done in the renderer, computing the gradients in higher precision, then dithering down to 32-bit RGBA.
I think I've seen the greatest appearance of banding when layering multiple semitransparent gradients on top of each other. Is there something that can be done about this? Otherwise I think the banding I've experienced has been working on displays set to a lower color depth.
