	* app/vectors/gimpvectors-export.c: save the vectors (or rather
	image) dimensions in the exported SVG.

	* app/vectors/gimpvectors-import.c: added SVG units parser and
	finished viewport handling. The parser now respects the size
	specified in the SVG and the image resolution. Should also handle
	nested SVGs correctly, but this is untested.
