GimpToolGyroscope is a tool widget providing canvas interaction for 3D rotation. The widget doesn't preset a UI, but rather facilitates panning, rotation, and zoom, by dragging the canvas, or using the keyboard. Rotation is expressed using yaw/pitch/roll angles (performed in this order). A zoom factor can be specified, which affects the magnitude of the rotation per distance traveled. The widget can operate in inverse mode, performing an inverse transformation.
