 * This is used for filtering out objects that you don't want.	For
 * example, you could make a filter for the ASL file requester so
 * that it only showed the files that were pictures, or even to
 * narrow it down to only show files that were ILBM pictures.
 *
 * Note that the Group ID's are in lower case, and always the first
 * four characters of the word.
 *
 * For ID's; If it is an IFF file, then the ID is the same as the
 * FORM type.  If it isn't an IFF file, then the ID would be the
 * first four characters of name for the file type.
