You are right, it's not very well stated, but I thought it would 
be obvious from the examples. The idea here is that when a struct 
does not define any copy constructors and the fields of the 
struct do not define any copy constructors, blitting is employed. 
If at least one field does define a copy constructor, then the 
above mentioned copy constructor is generated. Hope this sheds 
some light.
