#1251: Renderer.VML leaks style sheets

 Priority:  major                         |   Milestone:  2.6 Release
Component:  Renderer.VML                  |     Version:  2.5        
 Keywords:  createStyleSheet styleSheets  |       State:             
------------------------------------------+---------------------------------
 In Renderer.VML, the initialize method makes a call to
 document.createStyleSheet().  Each time it's called, it adds a new entry
 to the document.styleSheets array.  Each WFS layer that I create
 instantiates a new VML instance which, in turn, adds a new entry to the
 styleSheets array.  IE has a limit of 31 style sheets so adding numerous
 WFS layers quickly errors out.

 Since the VML class adds the same style sheet each time, I recommend
 changing the class to only add a single style sheet.
