Comment (by tschaub):

 Some random comments:
  1) We now use a simpler class syntax (no need for mentioning the
 prototype or using inherit) - see any of the other OL classes for an
 example.
  2) Other elements associated with controls also use the
 control.displayClass property as a class name.  This is generated by the
 Control superclass.  I think it is better to use this convention than to
 use the "loading" class name - it also gives app designers the ability to
 override the name.
  3) 200 and 300 look like magic values.  Does this stop me from having a
 partially opaque element over the whole map if my map is bigger than 200 x
 300?  I think these values are better as css declarations.
  4) Super trivial, but we also now need to separate the @requires comment
 block from other natural doc comments.

 I also think this would make a nice addin.  Would be good to start with
 something anyway.
