Fix error on area of cached coords and draw on right canvas. When zerioing, zeroing_coord() does not compute area of a cached coord and its descendant coords. It is fixed by eliminate empty areas of descendants and with special case of first non-empty area. In previous version, it always draw on canvas of root coord. It is fixed. Known issues: - It can not translate position of a pointer to a cached coord and descendants correctly.
