I'd like something more.
I was thinking something like:

dsize=w:h:keepaspect:round

for w,h, -1 means d_w/d_h, and 0 means original w/h

for keepaspect, 0 means nothing, 1 means force d_w/d_h aspect, by 
downscaling, 2 means the same, but upscaling, 3 and 4 mean the same, but 
with w/h aspect.

Shall I make a patch?...
