The piDogGeometry Module contains classes and methods that are required by piDogScrollingCanvas.

piDogGeometry.DoubleRect is a rect class that parallels most of REALbasic.Rect but uses Double values.
piDogGeometry.DoublePoint is a point class that parallels some of REALbasic.Point but using Double Values.

These items are available for you to use and/or borrow from.
