0.1.5 (2008-04-15):
	* Changed default max width/height from 1600x1600 to 2400x1200,
	  more appropriate for large line graphs.
	* Added the ability to tell KupoChart that a given axis contains
	  Un*x-style timestamps, which will be interpreted as (and displayed
	  as) dates. Added several settings pertaining to this feature.
	* Added a user-settable Y-axis margin (space between the high/low
	  points of the graph and the top/bottom edges of the plot area)
	* Added a 'DO_NOTHING' flag that supplementary tools like
	  colourslist.php can set. This allows scripts to pull in kupochart.php
	  without it actually plotting anything.
	* Modified colourslist.php to pull the colours directly out of
	  kupochart.php, rather than having to maintain a redundant (and
	  possibly out-of-date) copy within itself.
	* Included a new 'http_poster.pl' in the tools directory. This is a
	  tool to easily allow a user to pass data to a web service (such as
	  KupoChart) via POST instead of GET, allowing data submissions of
	  virtually unlimited size (GET is limited to several kilobytes on
	  most systems, due to hardcoded URL length limits and the like)
	* Added 'xpad' and 'ypad' options for line charts.
	* Added 'xlabelangle' and 'ylabelangle' options for line charts.
	* Included a new 'line-graph-by-time.php' demonstration file, showing
	  a practical way to graph time-based data.
	* Added 'docs/TODO'

	- Supported encoding types: text ('t')
	- Supported chart types: 2D pie ('p'), 2D X/Y line ('lxy')

0.1.0 (2008-04-12):
	Addition of 2D X/Y line. Code cleanup and internal
	documentation. Changed order of default colours to move
	the light and potentially difficult-to-read yellow colour
	towards the end of the list. Added detection of bad input
	for pie data type. Fixed handling of named colour values
	(e.g. 'red' as opposed to 'FF0000')

	- Supported encoding types: text ('t')
	- Supported chart types: 2D pie ('p'), 2D X/Y line ('lxy')
