SUMMARY		

PNMImport adds methods for importing Portable aNyMaps (PNM) as of Jef
Poskanzers pbmplus package. With the help of his package or the xv
program you can import ANY bitmap you like into your Smalltalk image,
store it as Smalltalk source code or in the binary BOSS format.
Directly supported formats include PBM, PGM, PPM, XBM.  Some of the
formats pbmplus supports: GIF, TIFF, JPEG, SUN Raster, XBM, XPM, PCX,
etc.
Don't ask me about import of GIF, TIFF, PCX and others because they
are compressed binary formats and would take to long to decompress
in pure Smalltalk code. Public decompression code is available in C
for all mentioned formats and PNMImport ist meant to be used only
*once* per image.

v1.1:	bitmaps saved with BOSS stay the same colors with xstdcmap
	cursor indicates reading, writing and processing of bitmaps
