27 * Functions for copying atoms properties.
29 * All of them receive, as the input, the property to be copied, the destination
30 * buffer, and a pointer to an offset in the destination buffer to copy to the right place.
31 * This offset will be updated to the new value (offset + copied_size)
32 * The functions return the size of the property that has been copied or 0
33 * if it couldn't copy.
