Describes the Symbol Unclutterer interactor

The IlvMagnifySymbolsInteractor is an interactor designed to move apart overlapping symbols displayed on a part of the view. This is done by clicking and holding down the mouse button and dragging the mouse over the view. It acts as a magnifying rectangle that displaces all the graphics related to the current SDM model displayed by the view. All the graphics contained in the rectangle are displaced making them easier to see.

The following figure shows an example of symbol uncluttering.

This interactor only has an effect on a view that contains an IlvGrapher managed by an SDM engine.
