@method get_image GdkCursor
@brief Returns a GdkPixbuf with the image used to display the cursor.
@return a GdkPixbuf representing cursor, or NULL
Note that depending on the capabilities of the windowing system and on the
cursor, GDK may not be able to obtain the image data. In this case, NULL is returned.
