That almost does it. You also need to define #bounds like this:

     def bounds
       FXRange.new([@fm.pos[0], @to.pos[0]].min,
                   [@fm.pos[0], @to.pos[0]].max,
                   [@fm.pos[1], @to.pos[1]].min,
                   [@fm.pos[1], @to.pos[1]].max,
                   [@fm.pos[2], @to.pos[2]].min,
                   [@fm.pos[2], @to.pos[2]].max)
     end
