* Added the -grs_longitude option, to specify the longitude of
Jupiter's Great Red Spot, in System II coordinates. This assumes
the Jupiter image has the center of the Great Red Spot at pixel 0
(at the left side of the image) in order to draw it at the right
position.
* Added the Icosagnomonic projection, contributed by Ian Turner.
* Fixed a bug where output filenames had an extra digit in some cases.
* Added the bump_map and bump_scale options in the configuration file.
* Added the -glare option to set the size of the sun's glare.
* An image map may be specified for the sun in the configuration
file now. A shade value is now required for the sun (should be
100, otherwise the sun will have a night side!)
* Added the -arc_spacing option to set the default angular
distance between great arc points. It used to be 0.1 degree, so
arcs smaller than this wouldn't get drawn.
* Fixed a bug where markers were not aligned properly when using
align = "above" or "below".
* Added warnings if options are specified in the [default] section
of the configuration file that probably shouldn't be there.
* Saturn's rings are now drawn properly when using "magnify" in
the config file.
* Added marker_fontsize as an option in the configuration file.
* Added the Bonne, Gnomonic, Polyconic, and Tangential Spherical
Cube (TSC) projections.
* Added the -proj_param option. Note that the -projection option
cannot be abbreviated to -proj anymore!
* Color cloud maps are now allowed.
* A color may now be specified with -background.
* fixed a bug where markers on the far side of a planet were being drawn
when they shouldn't have been
* fixed a bug where satellite were not drawn for some locales
* added -projection random; this picks a random projection
