 In RS_FontEngine::!GetTextMetrics the following code leaks memory:

 {{{
 RichTextEngine richTextEngine(m_pSERenderer, this, &tdef);
 bDone = richTextEngine.Parse(s, &ret);
 }}}

 There are actually a couple of memory issues in the !RichTextEngine class:

  * simply creating a !RichTextEngine and deleting it (no call to Parse)
 leaks memory
  * multiple objects of different types get leaked during the two calls
 above (e.g. there are calls to the !AtomTextRun constructor, but no calls
 to its destructor)
  * there are calls to malloc, but no matching calls to free (delete is
 used on one of the malloc'ed pointers, which is incorrect)
