/*****************************************************************************
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.
