689	Add some type-checking routines to psLib etc.	rhl@…	Paul Price	"The PS memory system allows us to check the type of a pointer (via the freeFunction in
the psMemBlock).  I propose that we add a new API
   bool psTypeEqual(void *ptr1, void *ptr2);
that would return false iff ptr1 and ptr2 were both non-NULL, and their freeFunctions
were different.

Note that this implies that we provide a (possibly trivial) freeFunction for _all_ types;
but this is needed for the proposal of PR 690"	defect	closed	high		IPP SDRS	unspecified	normal	fixed
