Non-final fields that are meant to be final are evil, I agree. However, 
in this particular case we can't initialize this field in the 
constructor because the target for this CPlatformWindow instance is 
unknown yet. We only get a reference to a Window object when the 
CPlatformWindow.initialize() is called which is happening after the 
constructor finishes execution. Thus the field has to be non-final.

Thanks for the review.
