it could be, but i don't particularly see the connection between the small 
icon size and the size of a panel. it would make more sense imho to tie to 
font sizes and theme border sizes since while pictures can be shrunk, text 
often has a hard limit on readability and the borders in the svg theme are 
similarly hard limits.

no, there isn't. not explicitly, in any case. the panel could stop at the 
largest minimum / preferred size, with an upper limit (so that crazy applets 
wouldn't result in a 100px high panel, for instance ;) ... e.g. something 
like:

minSize = qMax(16, largestMinSize(applets))
