/**
* This routine allows the user to add truetype,
* type1 or type1C fonts which will be used to disalay the fonts in PDF
* rendering and substitution as if the fonts were embedded in the PDF
* This is very useful for clients looking to keep down the size of PDFs
* transmitted and control display quality -
*
* Thanks to Peter for the idea/code -
*
* How to set it up -
*
* JPedal will look for the existence of the directory fontPath (ie
* com/myCompany/Fonts) -
*
* If this exists, Jpedal will look for 3 possible directories (tt,t1c,t1)
* and make a note of any fonts if these directories exist -
*
* When fonts are resolved, this option will be tested first and if a font
* if found, it will be used to display the font (the effect will be the
* same as if the font was embedded) -
*
* If the enforceMapping is true, JPedal assumes there must be a match and
* will throw a PdfFontException -
*
* Otherwise Jpedal will look in the java font path for a match or
* approximate with Lucida -
*
* The Format is defined as follows: -
*
* fontname = filename
*
* Type1/Type1C Font names exclude any prefix so /OEGPNB+FGHeavyItalic is
* resolved to FGHeavyItalic -
*
* Each font have the same name as the font it replaces (so Arial will
* require a font file such as Arial.ttf) and it must be unique (there
* cannot be an Arial font in each sub-directory) -
*
* So to use this functionality, place the fonts in a jar or add to the
* JPedal jar and call this method after instancing PdfDecoder - JPedal will
* do the rest
*
* @param fontPath -
* root directory for fonts
* @param enforceMapping -
* tell JPedal if all fonts should be in this directory
* @return flag (true if fonts added)
