This patch updates the documentation for arguments regarding the `Gizmo` type. - Corrected `select_id` doc for draw_preset_ functions. `-1` indicates that no selection ID is to be written, but previous docs incorrectly specified `0` instead. - Added missing doc for `target` argument for `target_set_handler` function.
