[GRASSGUI] wx.lib.floatcanvas

[Michael Barton]

I'm trying out posting to the GrassGUI list and wanted to show this to you
all. I just stumbled on to it. It is a new wxPython module aimed directly at
drawing maps in various coordinate systems. It even has a special toolbar
for zooming/panning.

We should probably switch to this. If I had known about it a couple weeks
back, it would have saved me hours of work as it has built in buffered
drawing.

Also, there is a new module for OGL drawing. These are vector objects that
can be manipulated.

Finally, I found a DrawXXXList class that will draw various shapes from a
list of coordinates.

One of these latter may be very good for a new way to render vectors.
