Macro to demonstate ways that transformation matrices can be used. This macro contains two procedures to scale a group of selected objects. While the scale method would probably be the easiest method to use for this operation in most case, the purpose of the macro is to show how matrices can work. One of the procedures performs the scaling in three separate, simple matrix transform operations, to show the use of translation and scaling separately. The other procedure combines translation and scaling in one matrix. This macro also uses the Graphic.ReferencePoint property, which is new in the v8 SDK. The macro will not run in v7, but it can still be loaded in v7 and viewed to see the code for the matrix transformations.
