one could add another effect set to KIconEffect which does what you want/need 
here. "Custom", so to speak. then apply this to every icon if set; though 
this leaves the overlay issue. we could abuse State here though by adding a 
value that causes the Custom effect to be applied to an icon. when 
drawOverlays calls loadIcon it would do so with (state ^ CustomEfffect) (or 
whatever it is called). this would address this problem:

.. since you'd have to specify that you wanted the custom effect
