suggestion: we keep the BorderSizes enum and do not enforce a specific size (I 
imagine theme engines to have a problem with it, at least Aurorae could have), 
but add a

int DecorationSettings::recommendedBorderSize() const

which gets the logic from breeze decoration. And it would probably need 
something like
bool DecorationSettings::sideBorders() const

which would be false for NoSideBorders and NoBorders otherwise true.

That way all Decorations which use the recommendedBorderSize() would have the 
same configured (sane) size. If a decoration doesn't use it and it provides 
bad useability: well then the user should report a bug against it ;-)
