Description: Modifications made by TIBCO Software for JasperReports >= 6.2 :
 #1 Fix for transparency issue with setClip method in PdfGraphics2D
 #2 Fix for transparency bleeding for Batik gradients
 #3 Fix for stroke opacity state in the create() method of PdfGraphics2D
 #4 Method to directly write AWT GlyphVectors to PDF for Indic scripts support
 #5 No character spacing in justified lines with a single word
