### Screwdriver
This tool is used for rotating nodes that support rotation. Right clicking a node with the screwdriver rotates the node around the X or Z axis depending on the player's position. Left clicking a node with the screwdriver rotates the node clockwise around the Y axis. Param2 types `wallmounted`, `facedir`, and `degrotate` are supported. The node is rotated 90 degrees for all param2 types except `degrotate` where the node is rotated by either 1.5 or 15 degrees. If the aux1 key (E) is held while rotating a `degrotate` node, the rotation angle will be increased by 4x.
