Say I have an image on my desktop. The file is 500k, so its thumbnailed.
I didn't do anything to the icon, so its showed at 96 pixels size, from
the thumbnail.

Now I select "Stretch Icon" from the menu and make the icon 200x200
pixels. If we continue to use the thumbnail for this it'll look pretty
fuzzy. What I would like is for it to switch to using the actual file as
the thumbnail for sizes > 128 pixels. This would make the icon look
crisp and nice.

That would be an ABI change at this point, and would seem to mean you
can pass any size into a GnomeThumbnailSize argument. It might have been
a good idea, but its a bit late to change now. Maybe we can add
something to get the pixel size of a GnomeThumbnailSize.

Not at the moment.
