 Through some trial and error, I have discovered that we can actually
 inspect and view symbols from a SymbolLibrary by using the Drawing Service
 APIs.

 SymbolLibrary resources use a DWF file (symbols.dwf) as the underlying
 data store, the process for enumerating symbols in a SymbolLibrary is
 simply:

  1. Create a temp Drawing Source pointing to this DWF file
  2. Invoke ENUMERATEDRAWINGSECTIONS on the drawing source. Each section
 returned represents one symbol from the symbol library.
  3. Invoke ENUMERATEDRAWINGSECTIONRESOURCES on each section of the
 previous result
  4. To extract the symbol image, invoke GETDRAWINGSECTIONRESOURCE on the
 href of the previous result whose role is "thumbnail"
