Ooh, yes, please! And the gdk scaling routines are very slow and 
memory-intensive for large-ratio downscaling, which is unhelpful too.

I've never been keen on embedded thumbnails - many apps ignore them, or 
don't update them after a change (e.g., main image gets cropped, but 
thumbnail does not - gthumb certainly has had issues with this in the 
past). Plus, orientation tag issues can be confusing (ifd1 may have its 
own orientation tag. Or not. Does the thumbnail use the ifd0 tag if 
there is no ifd1 tag, or is the thumbnail auto-rotated? It's unclear to 
me, anyway.) I don't trust them!
