Detailed Description

Bounds for a double trapezoidal ("diamond"), planar Surface.

The RotatedDiamondBounds Class specifies the same diamond as the DiamondBounds Class. The local X and Y coordinates will be interchanged internally for boundary checks. (This is opposed to the TrapezoidBounds, where X and Y are interchanged in the constructor.)
