True. I will try to find out. I was assuming that they did perturb the 
pixels.

The problem is that I need to create multiple thumbnails of specific 
portions of the GUI: how would I subset the metafile except by loading 
it into an image editor and taking a snapshot? Maybe one could apply a 
mask or clipping frame directly in the MF or PS code but there is a 
danger that you'd still be drawing the whole image behind the scene, 
which would be extremely inefficient: for N snapshots you'd be drawing 
the entire image N times.

Yes, given that I won't be showing the whole GUI but small details of 
it, they can be shown in real size.
