Gimp/libgimp/gimpprocedure.h
Jehan 9feaf02596 libgimp: use G_DECLARE_(DERIVABLE|FINAL)_TYPE macros for all Gimp*Procedure. 
Though I am not fond of these macros for our core code (it makes the
code more cumbersome especially for using private data in derivable
types), this definitely makes sense for public API, since it would allow
easier modifications with less chances of messing API/ABI stability.
