-/******************************************************************************
-** Filename       : imageSgi.cpp
-**                  UNCLASSIFIED
-**
-** Description    : Utility to read SGI image format files.  This code was
-**                  originally a SGI image loading utility provided with the
-**                  Mesa 3D library @ http://www.mesa3d.org by Brain Paul.
-**                  This has been extended to read all SGI image formats
-**                  (e.g. INT, INTA, RGB, RGBA).
-**
-** Revision History:
-**   Date       Name   Description
-**   06/07/99   BRC    Initial Release
-**
-** Note:
-**
-** The SGI Image Data (if not RLE)
-**
-**   If the image is stored verbatim (without RLE), then image data directly
-**   follows the 512 byte header.  The data for each scanline of the first
-**   channel is written first.  If the image has more than 1 channel, all
-**   the data for the first channel is written, followed by the remaining
-**   channels.  If the BPC value is 1, then each scanline is written as XSIZE
-**   bytes.  If the BPC value is 2, then each scanline is written as XSIZE
-**   shorts.  These shorts are stored in the byte order described above.
