> For some text in some documents, getStringWidth() returns an incorrect value.  In some cases it returns zero, which is clearly not correct.  In others, it returns something that is too short.  An example of this follows:
> On the page, this text is part of text that reads "Cash flows from".  The text in question is delivered to flushText in PDFTextStripper as multiple TextPositions, and the ones below are those containing "w" and the next one containing "s fr".
> The first one looks like this:
> TextPosition: "w"  
> getX=62.824474 
> getWidth=6.731968 
> getWordSpacing=0.000000 
> getWidthOfSpace=2.224000 
> getXScale=1.000000
> glyphFactor=999.999939, getXScale=1.000000, getStringWidth=814.000000, calculatedFontWidth=0.814000 
> averageWidth=0.546769, 
> widthUsingSpaces=2.224000  
> widthUsingFont=0.546769
> Note that, according to getStringWidth(), the width of this text is 0.841 meaning it would end at 62.82 + 0.841 = 63.66.
> According to getWidth(), it ought to end at 62.82 + 6.73 = 69.55.
> When we look at the next chunk of text:
> TextPosition: "s fr" 
> getX=69.336563 getWidth=12.518410 
> we see that it does in fact start immediately after the previous one -- so the width from getStringWidth() for the first one was incorrect.
> The font is a PDType1Font and its name appears to be "YOTPKO+HelveticaNeue-Bold*1".
