3.2g	(93/04/26)

    ENHANCEMENTS:
	- much faster close colors
	- piping from/to compressed files now handles GNU's gzip (.z)  format
	- added XpmColorKey attribute - ability to specify which visual's
	  colors to use (ie: now it's possible to read in a pixmap in a
	  color visual, but use the colors specified for monochrome).
	- added -mono, -grey4, -grey and -color options to sxpm to demonstrate
	  the XpmColorKey attribute.
		- Jason Patterson <jasonp@fitmail.qut.edu.au>

    BUGS CORRECTED:
	- fixed bug where redefining "None" as a pixel stopped mask generation
	- minor SVR4 defines for <string.h>
	- fixed annoying closecolor bug related to read/write color cells
	- fixed minor bug in color value -> pixel overloading
	- manual updated to include new red/green/blue closeness attributes
		- Jason Patterson <jasonp@fitmail.qut.edu.au>

	- the top Imakefile was missing the depend target
	- sxpm/Imakefile fixed so that -L../lib is set before the standard
	  library location.
		- Vivek Khera <khera@cs.duke.edu>

	- lib/xpmP.h now defines bcopy as memcpy for VMS (required by recent
	  versions of VMS)
		- J. Daniel Smith <dsmith@ann-arbor.applicon.slb.com>

	- the lib/Imakefile didn't work with X11R4.
