Simple image loader and image shape. - img_ldr.c is a simple image loader that rooted on a directory specified when a loader instance been created. - sh_image_t is corresponding shape of image tag in SVG. - This changeset is still buggy. It need more testing. - svg2code.py is not ready for image tag.
