Octplot 0.3.0 Is out

Hi all,

OctPlot release 0.3.0 is out and available at

http://sourceforge.net/projects/octplot/

As usual 0.x.0 releases incorporate new features which will (with your
help) improve and stabilize by the 0.3.5 release.

New Features:
1) 2D surfaces -- the Z coordinate determines the color.
   relevant functions: pcolor, colormap, colorbar, specgram, specgram_demo (in
   the demos directory)
2) Patch objects
   relevant functions:  patch,area
3) Zoom stack -- in a figure, drag with left mouse button to zoom,
   shift left-click to autoscale, right-click to go back in zoom stack
4) Better manual control of tick placement & labels. This was a priority
   because, frankly, the automatic stuff is not great
   relevant axes properties: {x,y,z}ticklabel , {x,y,z}tick
5) Various bug fixes

I reshuffled my priorities so TeX-like super/subscripts will need to
wait (although the curious can take a look at the femtoTeX directory)

Enjoy and submit bugs
