Swap X (swapX)
The Swap X property reverses the direction of the X-axis.
In the Properties view, this property is the Swap X property in the Orientation category.
By default the positive X-axis extends 90 degrees right (clockwise) of the positive Y-axis; if, for example, the Y-Axis points to north, the X axis will point eastward. Setting this value reverses the direction so that (in the example) the X-Axis would point to the west which is 90 degrees to the left (counter clockwise) of the Y-Axis.
Type: Boolean. The default value is FALSE.
