Perhaps I'm missing something, but shouldn't this be part of the initialization of the axes in graphics.cc?

Something like what is below (I haven't tried this and would be surprised if I've got it all correct).

-------------------------------------------------
viod
axes::properties::init (void)
{

[...]

xset (xlabel.handle_value (), "handlevisibility", "off");
xset (xlabel.handle_value (), "horizontalalignment", "center");
xset (xlabel.handle_value (), "verticalalignment", "cap");
xset (xlabel.handle_value (), "interpreter", "none");

xset (ylabel.handle_value (), "handlevisibility", "off");
xset (ylabel.handle_value (), "horizontalalignment", "center");
xset (ylabel.handle_value (), "verticalalignment", "bottom");
xset (ylabel.handle_value (), "rotation", 90.0);
xset (ylabel.handle_value (), "interpreter", "none");

xset (zlabel.handle_value (), "handlevisibility", "off");
xset (zlabel.handle_value (), "horizontalalignment", "right");
xset (zlabel.handle_value (), "interpreter", "none");

xset (title.handle_value (), "handlevisibility", "off");
xset (title.handle_value (), "horizontalalignment", "center");
xset (title.handle_value (), "verticalalignment", "bottom");
xset (title.handle_value (), "interpreter", "none");

adopt (xlabel.handle_value ());
adopt (ylabel.handle_value ());
adopt (zlabel.handle_value ());

adopt (title.handle_value ());
}
---------------------------------------------------

Notice that I've included other properties whose defaults differ from those for a text object.
