Release notes for 0.3.9

This release added some new features any many bug fixes. For a full list, 
please consult Changelog. A summary of noteable features:

* added layering support - objects are now layered in the order their 
handles are arranged. See the layer_demo
* added arrowheads support lo lines using the arrowhead, arrowlength, 
arrowwidth , & arrowratio properties -- help line_props
* new properties for axes: box, xaxislocation, yaxislocation. 
color, xcolor & ycolor can now accept "none"
as a value 
* axis command improvements: now accepts 
on/off/equal arguments
* box, quiver, plotyy, stem, barh, & pareto added.
* new and probably improved figure handling

Release notes for 0.3.5

New features:

* toogle_octplot now clears all ploting commands when octplot is
toggled off, so normal gnuplot usage should be possibel after an even
number of toggles (Thanks to the octplot debian porting team).
* Markers can now be filled - MarkerFaceColor & MarkerEdgeColor line 
properties
* zoomstack is now axes specific. Try the right mouse button to go back in the
stack, shift-left button to autoscale.
* surface can now handle matrix,vector or empty xdata & ydata
internally which makes for faster drawing and lower memory usage
* legends - legends are still in their infancy. However some control over
their appearance is possible. It is also possible to set the line
legends using the octave ";;" notation i.e. plot(1:10,"b-;blue line;")
-- help legend_props,legend.
* pie,stem charts -- help pie, help stem
* bars - bar & barh are starting to look good thanks to efforts by Michael
Schmid -- help bar,barh

Release notes for 0.3.0

New features:

* patch -- help patch, help patch_props
* surface objects - OctPlot is still 2D, so the Z coordinate of the surface 
determines only color as defined by the figures colormap and the axes' clim
-- help surface_props, help pcolor, help colorbar
* better manual control over axes ticks & tick labels -- help axes_props

Release notes for 0.2.5

New features

* install target -- ./configure --help
* rotatable text --  help text_props
* eps,ps,pdf,png,jpg hardcopy -- help print


Release notes for 0.2.0

Major new features in this release:

* subplots -- look at subplot.m
* log axis -- look at loglog.m, semilogx.m, semilogy.m
* contour -- look at contour.m
* missing value support using NaN
* better auto ticks
* better eps output -- look at print.m

RoadMap:

Release 0.2.5 

mainly a bug fixing release 


Release 0.3.0

The "Text release": Axis labels, tick marks, legends, and titles should
work flawlessly. This includes a complete overhaul of the text object:

* move to the FTGL rendering library for rotateable, anti-alised fonts.
* adding a "femtoTeX" parser which will parse at least the following
TeX constructs: ^ _ {} \Alpha-\Zeta \alpha-\zeta

These enhancements will affect all text objects including axis labels,
titles, and tick marks


Release 0.3.5 

mainly a bug fixing release 


Release 0.4.0

The "2D release": I will add all the missing 2d functionality -- patch
objects and the following functions

patch, piechart, bar, area

maybe arrow and errorbar


Release 0.4.5 

mainly a bug fixing release. 

At this point octplot should prove to be a viable alternative to gnuplot
for 2d graphs
