247	Return Value for New psMetadataLookup Functions	calvin.harman@…	eugene	"Section 5.3.3 adds new functions: 
psS32 psMetadataLookupS32(const psMetadata *md, const char *key);
psF64 psMetadataLookupF64(const psMetadata *md, const char *key);

If the key is not found, 0.0 is to be returned. What if the key is found and 
its value really is 0.0? Perhaps a third argument for status should be added to 
these functions, which could be checked to determine if the key was found? I'm 
not sure that you'd want to put an error statement directly in these functions, 
since there may be times when you don't care if the item was found."	defect	closed	high		PSLib SDRS	unspecified	normal	fixed
