V-Linear Meter Orientation

This example demonstration various orientations for vertical linear meters.

In a vertical linear meter, the scale labels can be positioned on the left or right side of the meter scale. This is controlled by the last argument to LinearMeter.setMeter, which can be Left or Right.
