Version 1.01
* Added support for line-thickness, read-offset, and write-offset.
* Made the broken amplitude scale black instead of the fill colour.
* Converted the ever-expanding list of arguments to GetProgramParameters into a
  simple class for ease of adding new parameters in the future.
* Fixed a bug in the program parameter reading routine that was making all
  arguments (including paths) lower case.

Version 1.02
* Fixed the verticalscale routine that draws the dashed horizontal lines so
  that the base line is solid, not dashed.
* Ported to Win32
* Added program parameter time-line which indicates whether or not the time in
  seconds should be written at the bottom of the image. 

Version 1.03
* Fixed PS code so that newpath etc. commands are not repeated rather
  called with postscript functions.

Version 1.04
* 16/12/03 Added exponent option to raise rms to this argument: helps
  compress dynamic range and make very low signals show up

        

TODO

* Check read-offset write-offset for influence on each other
* Report the maximum RMS of the whole batch, with the file it occured in.
