Allow Reshaping Callout Leader Widths

Idea created by jeg728 on Apr 30, 2013
    Sometimes a callout box has to be placed at a very specific location on a map or exhibit so as not to cover up other data, labels, or features.  This often results in less-than-ideal "chunky" callout leader widths.  The ability to resize the callout leader width to make it narrower (or wider in some cases) would be great!!   Adding resizing handles where the leader meets the callout box would be great.
