I didn't see that there was a patch attached. I would suggest a different
solution here. See the attached [^pdfcolor.patch].
=> The target Graphics2D needs some way to get the original colors. I would
suggest a small java.awt.Color derived class, which just carries this PDColor
information. So if the Graphics2D wants that it can use that. Otherwise nothing
changes.
Currently I always have to override getPaint() in PageDrawer to get this
information. With this patch that would not be needed any more.
