Armin Le Grand 4fa8df7320 Resolves: #i119735# missing css.svg.SVGWriter when using GraphicProvider
missing implementation for com.sun.star.svg.SVGWriter when using
GraphicProvider

Adapted patch provided by Sven Jacobi (thanks), added some fixes/cleanups to
make it work with all kind of graphics (SVG, Bitmap, Metafile)

(cherry picked from commit 891011181285d7ad54984ffd05ed44d825a70647)
