It's an option but won't that look a bit funny first the image is fuzzy 
and then after quite some CPU cycles they will get crisp? And people 
using high zoom level will see a high cpu usage.

Another idea. Thumbnails could be saved in the size specified by the 
app. All programs using thumbnails just read the thumbnail. If a 
thumbnail is requested by an app it first reads the size of the preview. 
If that size is large enough or within a certain range it will use that 
one otherwise it creates a new thumbnail file.
Option there of course is overwriting the old one or saving it to a new 
file so that both sizes will be available.

What do you think about that?
