It's a multistep process to get it all integrated. I couldn't find
anything specific online for making a custom widget with gtk3 so I have
copied the structure and methods from the gtkscale/gtkrange widgets.

http://git.gnome.org/browse/gtk+/tree/gtk/gtkscale.c?h=gtk-3-6
http://git.gnome.org/browse/gtk+/tree/gtk/gtkrange.c?h=gtk-3-6

I got it to the point where it the class is building and init() is being
called but I am having a problem with assigning the correct TYPE for
GTK_METER and getting the draw/realize methods to fire.

If anyone feels like chipping in some suggestions for how to get past this
step I'm all ears :-)
