/*
* Global file class definitions *
*
* The global class definition gives you some primary information about the
* global file type. This is useful if you want to know about e.g. a file
* is packed.
* For example, a PowerPacker password crunched executable gets a global
* class value of $0007 ( EXECUTABLE|PACKED|ENCRYPTED )
*
* Note that on some special data formats, like e.g. IFF-ILBM files with
* crunched bitmap chunks, bit 1 isn't set. If an IFF picture was packed
* (e.g. using Xpk), FileID.library would report an Xpk compressed file,
* not an IFF picture. Do not mischange this.
* For example, NoisePacker modules or JPEG pictures DON'T have bit 1 set,
* even when everybody knows that these files contain packed data. Got me ?
*
* FIGFC_GRAFIC_IMAGE does NOT include any 2-D or 3-D rendering data formats,
* like imagine objects, vector fonts etc. Somtimes, it was really hard to
* decide if this bit should be set or not. So please treat bit #5 as a kind
* of help, not as warranty.
