This design provides a visualization of the position and orientation of a Frame. A Frame is a coordinate system. This representation is a 3-4-5 triangle in the X-Y plane, with the longer leg in the X direction. A small Z-oriented segment shows the Z-axis. The representation, like Plane and Ray, is sized to the view. The representation is the same as that provided by the renderFrame: attribute on FrameMixin.
The size of the frame representation. This size is actually the length of the Z-oriented segment. All other parts are sized relative to it - the X-leg is four times longer and the Y-leg is 3 times longer. The default value is one-tenth of the window width.
