** PURPOSE:	Convert input RGB data rows to jpg tile-set and thumbnail and optionally 
**              a full-size jpg for downloading as well.
**		Call jpgTiles with image width and height and outdir and outpath 
**              Quality settings can also be optionally specified.
**                 [-quality N|-variable 50 60 70 80 85]
**              Currently just operates on one output image tileset and stops,
**              so run the program again for each input image.
**
** NOTES:
**      Keeps the same size image as input and uses RGB 3-band 24-bit color
**      with default quality 75%. Caller must create a subdir under outdir with the root name of
**      the infile, i.e. infile/  and it puts the tiles for levels 0-4 there, 
**      each higher level zooms out by 2 in both dimensions.
**      N is % quality, from 3 to 95 and is optional, otherwise uses libjpeg default (75%).
