Font ascent and descent in ITextTextRenderer #137

In the method getFSFontMetrics of ITextTextRenderer (line 55), BaseFont.BBOXURY 
and BaseFont.BBOXLLY are used to calculate the ascent and descent of the font 
while this values are provided by iText.
I propose the following change :
    result.setAscent(bf.getFontDescriptor(BaseFont.ASCENT, size));
    result.setDescent(-bf.getFontDescriptor(BaseFont.DESCENT, size));
With this, the markers of list items are better vertically centered.
