Ah, because it's static?
You can't remove the static keywords from the method signature, when it's  
ment to be used this way:
t3lib_iconworks::skinImg() etc.
Or can we, because PHP bullshit allows as to call them, even without  
having it declared sa static?

I currently have no clue, if there's a way to extend a static class (so if  
we remove the final keyword). But XCLASSing it isn't possible, as calls to  
the static functions aren't handled through t3lib_div::makeInstance().

So I wonder, how it works with Stephan's patch in his skin extension, but  
as it obviously does, maybe we should give the chance, to extend  
t3lib_iconworks.

Sorry.. nearly all my PHP-OO knowledge has been replaced by Java and C#,  
so could please sb. tell us, why we could / should (not) do this?
