      public final class PgRuler
      extends PgJvxSrc

  A ruler is 2d or higher dimensional space is determined by an origin, a direction of its axis and a normal for drawing hashings. The spacing and labeling of hashings may be controlled or automatically computed by a ruler.

  Rulers are used as components of PgAxes but additionally may be used individually to measure distances.

      Description copied from class: `PgGeometry`
      Update method of geometry updates registered panels, update listeners, and invokes a repaint in the registered displays. Usage:
      1. event == this : geometry has changed, all panels will be updated.
      2. event == null : geometry has changed, no need to update a panel.
      3. event == a panel : geometry has changed, all panels except 'panel' will be updated.
      3. event == else : unhandled event, error.
      Panels are not updated if they have not been created yet, or if they are not visible. Any update is forwarded to the parent of the geometry with the geometry as event. Any update is forwarded to each registered display with the geometry as event which leads to a repaint of the display.
      Specified by:
        `update` in interface `PsUpdateIf`
      Overrides:

To use this method you simply need to pass it an endpoint from which a measurement is made from the currently defined ruler origin set via #setOrigin(). Hashings will only be automatically visible if measurements are made in the xy,yz, or xz perspectives. For the arbitrary perspective case you must explicity give a direction in which to draw the hash, else results may be unpredictable.

    - #### setEnabledAutoHashing

          public void setEnabledAutoHashing(boolean flag)

      Flag is axes in "absolute unit mode" will automatically adjust to a 'good' viewing scale based on the bounding box passed into configure(). Essentially the scale jumps up or down by a factor of 10 if any length of the bounding box is streched to 10*currentscale + 10*currentscale/2 or squashed to currentscale/10-currentscale/10*2. In other words, an attempt is made to maintain approximately 10 hashings over each ruler. This need not apply to the "partitioned ruler mode" as the ruler is already subdivided. This is true by default-set to false if many more hashings are needed. Note that in this mode a single minor hashing will be placed between each major hashings whenever a reconfiguration is needed.
      Since:
        JavaView 3.62.013

    - #### isEnabledAutoBounds
