Biggles

===================

* Phil Kromer contributed the new ColoredPoints and Density components.
See example9.py for details.

* Todd Fox contributed Makefiles for building with MS Visual C++.

* Can now specify the width/height of postscript output, by passing (e.g.)
width="5in" or height="10in" to the functions which produce postscript
output. Default values are in the [postscript] section of config.ini.
The old [printer]/paper option is now [postscript]/paper.

* Added UpperLimits, LowerLimits components. These produce symbols
with half-arrows indicating the true value is below/above the
point.

* Added TeX codes \`,\',\^,\",\~ for character accents.

===================

* Mike Romberg fixed bugs related to packaging biggles with imputil.

===================

* Spiros Papadimitriou contributed an experimental piddle port.

* You can now specify partial ranges for plots. So "p.xrange = 2, None"
will set the lower bound of the plot p to be 2, and the upper bound
will be guessed from the data contained in the plot.

* Replaced "!= None" with "is not None" everywhere.

* Fixed bug with added space in scientific notation ticklabels.

===================

* Martin Lamar ported the code to Windows.

* Replaced "== None" with "is None" everywhere (again thanks to Martin).
This should fix crashes with recent versions of numpy.

===================

* Clipping!

* Better performance for plots with lots of data. Parts of the code
were vectorized, and a new integrated libplot interface was written.
Biggles no longer uses the python-libplot module.

* Jamie Mazer contributed code for Matlab emulation, accessible by
"import biggles.matlab".

* Added the multipage() function for multipage postscript output.
Thanks to Olivier Andrieu for the original patch.

* Changed the default plot window size to 512x512 from 570x570.

* Bug fixes: better tick generation on huge-ranged log axes; the
"thousand tiny lines" problem with contour plots.

===================

* Completely rewrote FramedPlot. Fully backward compatible with
the old FramedPlot, it adds a tremendous number of new features.
CustomFramedPlot is now deprecated.

* Configuration options are now read when objects are instantiated,
instead of during class definition. This means you can change them
in the middle of a script, using the new configure() function.

* Added read_rows(),read_matrix() functions. They read text data files,
returning a list of rows and a matrix, respectively. Numeric Python
arrays are returned by default. The readcolumn() function has been
renamed read_column().

* TeX font control sequences \it and \bf are now recognized. Spaces
are no longer ignored during math mode.

* You can now specify single characters as plotting symbols.

* Added DataBox/PlotBox components.

* Added .align_interiors option to Table.

* Added .drop_to_zero option to Histogram.

* Added .title_style attribute to all containers.

* The container methods .save_as_XXX() were renamed .write_XXX().
While the old names are not deprecated, they will no longer
appear in the documentation.

* Bug fixes: fixed crash when used by a CGI script, dropped minus
sign for axis labels which are powers of ten, compile problem on
Suns.
