well, we do clear the renderer, and this is already done for system theme 
color following svgs. 

problem is that, as you note, the on-disk cache is not cleared (Svg relies on 
Theme dropping the cache on such change) and short of doing bookkeeping of all 
id's cached in a given unthemed-but-colored svg there is no easy way out. (and 
then there are edge cases where things change while the cache is not 
maintained, e.g. the app is closed or the svg object destroyed.)

that's very unfortunate, really :(

i'm pretty well finished implementing it already.
