    Fix null pointer dereference on very large images.
    
    If xcursorgen encounters a PNG file which is larger than 32767 pixels
    in width or height, a null pointer dereference occurs because the
    return value of XcursorImageCreate is not checked.
    
    The largest possible value is 32767 for libXcursor, which is a hard
    coded limit due to a 16 bit integer used (0x7FFF).
