Vista - Sidebar Slide Show - needs image dithering?

I'm just putting this out there, as someone who recently switched over
to Vista. I had a great deal of fun getting my sound card and
wireless adapter to work, but now it seems everything's running fine,
and I'm going through the motions of getting my desktop back in
working order. I'm especially liking the Sidebar - as someone who's
used plugins everywher from Trillian to Google to Yahoo, I'm quite
used to getting my info at a glance, and it's nice to have a more
unified and integrated solution for that here, and a pretty one, too.

One thing bugs me, though: I'm using the Slide Show gadget to display
some photos and line art I've had for awhile, and I like having it
there as a bonus, even if it is likely sucking some CPU cycles from my
desktop use. But while the little thumbnails look nice when
displaying big things like landscapes, it doesn't handle large images
and line graphics so well - they look all jagged, like with a rough
resize. Not nearly as pretty as I know they can.

It bugs me even more because I know IE can apply image dithering when
zooming webpages, but there's no such option in this gadget.

Anyone else wishing for this, or know of a solution besides waiting
for someone to work on a better slideshow gadget?
