What about re-running EPS picture through GS when it's resized?

|
|   gs -r20x30 picture.eps

EPS is naturally subset of PS.
It can have embedded picture, but this is mostly for preview (placeholder in 
DTP/Word Processor program)
WP usally uses this placeholder for formatting, columnt layout, etc,. and 
when printing it sends EPS (to vector device, like PostScript printer) or 
printer driver converts it to raster format with printer's best resolution.
 
If curent KOffice has problem with proposed above, what about running 
("distilling") EPS through eps2ps filter, and inserting unmodified PS 
illustration in KWord?
The best, of course, is to try to convert EPS to SVG, but SVG part is still 
not here :-(
// and conversion filter, probably, also not written.

I guess GhostScript itself is enough. :-)
