Remarks

This method is called to get the extent of an identifier or an expression starting at a specific location. The location can be in the middle or at the end of the identifier or expression.

This method is an implementation of the GetWordExtent method on the IVsTextViewFilter interface.

The base method validates the parameters and forwards the call to the GetWordExtent on the Source object that was obtained in the ViewFilter constructor.
