When manipulating svg file, the implementation of SkSVGCanvas will be used instead of the
implementation of SkCanvas, so the api are tested against SkSVGCanvas. In addition, there are
more api need to be covered in the function fuzz_canvas. As a result, the main changes are to
add new DEF_FUZZ for SkSVGCanvas and to modify fuzz_canvas to increase the coverages of api.
