    • summary
      a custom _Line to accomodate multi-dimensional values
    • description
      a normal dojo._Line is the curve, and does Line(start,end)
      for propertyAnimation. as we make more complicatied animations, we realize
      some properties can have 2, or 4 values relevant (x,y) or (t,l,r,b) for example
      
      this function provides support for those Lines, and is ported directly from 0.4
      this is a lot of extra code for something so seldom used, so we'll put it here as
      and optional core addition. you can create a new line, and use it during onAnimate
      as you see fit.

    • example
      
      	// this is 10 .. 100 and 50 .. 500
      	var curve = new dojox.fx._Line([10,50],[100,500]);
      	// dojo.Animation.onAnimate is called at every step of the animation
      	// to define current values. this _Line returns an array
       	// at each step. arguments[0] and [1] in this example.
