Remarks:

If raster file name is an empty string, or starts with "data:image", SVG filter embeds raster data to the image file, otherwise it saves it in a separate file, using the format specified by IG_vect_raster_set_fileformat, and references it in the vector file.

According to the SVG specification, readers shall support at least PNG and JPEG formats.
