Bug 43357

[PATCH]

In PDFGraphics2D image are rescaled 2 times in the same way.
First is rescaled by java.awt.Graphics2D and put in BufferedImage 
that will used to write PDF code. Second is rescaled by trasformation 
matrix in PDF code.

This will cause a resulting image that have very low resolution (pixelized). 

Before look at PDFGraphics2D code I try also to change DPI but this has 
not effect.
