title: Get font height/weight from TextRenderInfo how?
body: <p>When I parse an existing PDF using iText(Sharp), I create an object which implements IRenderListener which I pass into PdfReaderContentParser.ProcessContent() and sure enough, my object's RenderText() gets called repeatedly with all the text in the PDF.</p>
  
  <p>The problem is, the TextRenderInfo tells me about the base font (in my case, Helvetica) but I can't tell the height of the font nor its weight (regular vs. bold).  Is this a known deficiency of iText(Sharp) or am I missing something?</p>
