Sorry for that. I also fixed some other minor things in that commit. Do you
plan to support vector data as well?

What I am not sure about is the usage of pygrass here. The problem is if we
would like to integrate it more in GUI. Currently when you click on the
g.gui.tplot in menu, a standard generated dialog opens and when you fill
the params and press ok, the actual plotting gui shows up, which is
cumbersome. The menu entry could bring directly the tplot, however then
there is a possibility of crashing entire GUI when something goes wrong
(because of using ctypes in pygrass). So one option is to call some t.*
module but there is no t.rast.what only t.vect.strds.observe which requires
vector map. Another option is to wrap the pygrass code and call it as a
subprocess. I don't have time to look at it more now, but we should be
aware of this.
