/*****************************************************************************
	This VC++ project was used for developing and testing RAINBOW, 
	the re-entrant JPEG/PNG/GIF/TIFF-decoder made originally for a 
	home-brew Operating System.  

	It's quite verbose with a lots of comments and limited error-checking. 

	RAINBOW decodes and converts images to memory-bitmaps, in Direct Color
	15/16/24/32 bit-per-pixel BM-format that matches the video card's frame 
	buffer. The PCI SVGA cards I used (S3, Cirrus, ATi, SiS) were programmed 
	to one of these Direct Color Modes using a Linear Frame Buffer. 

	VC_RAINBOW implements different clients for RAINBOW and writes bitmaps 
	as BMP-files on disk. Main is only responsible for opening/closing files 
	and call the appropriate BMP-converter client for RAINBOW. 

	Project dependecies:
