+*    NAME
+*	IFFLib_SaveBitMap -- save the planes of a BitMap as an IFF-file
+*
+*    SYNOPSIS
+*	result = IFFLib_SaveBitMap( filename, bitmap, colortable, flags )
+*	D0                          A0        A1      A2          D0
+*
+*	BOOL IFFLib_SaveBitMap(char *, struct BitMap *, UWORD *, ULONG )
+*
+*    FUNCTION
+*	Save the planes of a BitMap as an IFF-file, optionally with a
+*	colortable. The IFF file will contain the following chunks:
+*
+*	FORM  -  The IFF header, with the type ILBM
+*	BMHD  -  The BitMap Header structre
+*	CMAP  -  The color map, this chunk is omitted if colortable is zero
+*	CAMG  -  The Amiga ViewModes word, contains the special ViewModes
+*	         information (HAM, LACE, HIRES ...)
+*	BODY  -  The (crunched or uncompressed) picture
+*
+*   INPUTS
+*	filename    - Name of the IFF file to create
+*	bitmap      - Pointer to the BitMap holding your picture
+*	colortable  - Pointer to an Amiga ColorTable structure or zero
+*	              (if colortable = 0, no CMAP chunk will be generated).
+*	flags       - Bit 0: 1 = Use the "CmpByteRun1" compression algorythm,
+*	                     0 = Save the file uncompressed
+*                      Bit 7: 1 = This is a HAM (Hold and modify) picture
+*	                     0 = This is a normal or Extra-Halfbrite picture
+*
+*   RESULT
+*	Non-zero if successful, 0 if error, Call IFFLib_IFFError() to know
+*	more about the reason of the failure
+*
+*   NOTE
+*	This routine needs 620 bytes of stack space
