 * Considering large pixmap is not a normal case, to keep

 * When deal with a large pixmap, it split the working
 * rectangle into serval boxes, and each box fit into a
 * corresponding fbo. And then the rendering function will
 * loop from the left-top box to the right-bottom box,
 * each time, we will set current box and current fbo
 * to the box and fbo elements. Thus the inner routines
 * can handle it as normal, only the coords calculation need
 * to aware of it's large pixmap.
 *
 * Currently, we haven't implemented the atlas pixmap.
