Add a geometry method to drawables
Add a geometry method to drawables

The drawable class already has a geometry function which can be called
when given a drawable as first argument. This commit uses the same(?)
hack that is used for drawins to make this method also available on
individual objects.

This makes the following code work:

    drawin{}.drawable:geometry()
