Basic external-graphic support now available for PDF and SVG painters (for PDF: RenderedImage, SVG, JPEG, CCITT and Java2D, for SVG: embedded SVG and RFC2397 data URLs containing PNG and JPEG images)
Change to IFPainter: added support for foreign attributes for the "image" tag.
PDFContentGenerator introduced to hold the most important objects for PDF generation (unification for renderer and painter).
Re-routed most image handling through the new image handling code (not fully done, yet, some code duplication remains).
