 The current Redline widget is half-baked in terms of functionality. Some
 of the problems include:

  * Redlines are not actually part of the map, and thus are not plottable
 when using QuickPlot or similar rendering APIs.
  * Redlines do not use the MapGuide Layer Definition for style
 configuration
  * Redlines cannot have labels defined and attached to them
  * Redlines can be downloaded to GML, but lacks support from Autodesk's
 own geospatial products. Ever tried overlaying or importing redlines
 downloaded from this widget in AutoCAD Map? Me neither. Redlines should be
 downloaded as SDF or some other better supported format.

 Fortunately all these pain points can be solved by throwing out the
 existing redline widget as is, and replacing it with a new redline widget
 that is based on the Autodesk's original Markup example for the basic AJAX
 viewer. Why this example wasn't used as the original base of the Redline
 widget is anyone's guess, but it satisifies all the redlining requirements
 that the current redline widget dismally fails to meet.

 This has already been implemented in our github fork (#460), this ticket
 is to track progress in porting this functionality back to the official
 repo.
