This can be done according to the spec by making two directories with 
Type=Scalable and then having different values for MaxSize and MinSize for 
the directories.

I don't know if the KDE implementation handles this, but i believe so.

Another way to handle this is to have pre-rendered versions of the icon at 
small sizes, and place those directories before the scalable one in the 
theme.
