Newly reimplemented virtual methods will not be called by inheritted
classes. (if KFooStyle (derived from KStyle) reimplements polish() and calls 
KStyle::polish then this it will be resolved to QStyle::polish at compile 
time when KStyle does not reimplement polish. Adding a reimplementation 
afterwards will make KFooStyle still call QStyle::polish instead of your 
new reimplementation.
