[pdf-devel] type 3 functions

[Hardy Falk]

Hi.
The occurence of function objects in a type 3 function 
dictionary makes pdf_func_t into a recursive data type.
How is such an pdf_ obj_t constructed in the first place? 
Afaik, pdf_obj_t constructors make deep copies of their 
arguments. Building a deeply nested structure in this way 
seems odd to me. It might be easier to transfer ownership
on object creation and do everything else with shallow copies.
Just my two cents, of course...
