BUG:	Use of the cmap() function for combining 3 images into an 8-bit
 	PseudoColor image results in a garbage line at the top or bottom
	of the image (depending on format), this line is some random color.
	The problem is that the last image line processed is not flushed
	properly to the temp image used in the conversion.  The solution
	requires a code change to properly flush the image buffer.  

STATUS:	Fixed for the next release.  The IMCNV external package version of
	the task is updated with the fix or sites can contact site support
	for instructions on patching the system.  Workarounds are to write
	a 24-bit image instead and do the conversion using host tools, e.g.
	write a 24-bit rasterfile and convert to GIF afterwards.
