if true, then the "From" option is automatically avaiable in GetPoint.
The GetPoint "From" option is never visible on the command line and the user must
type the complete option name to activate the "From" option. When the GetPoint "From"
snap is enabled, the user set/change the base point during GetPoint by typing "From" and
picking a point.
A related option is the builit-in distance from base point constraint that is can be set
before GetPoint is called by passing a value to GetPoint::ConstrainDistanceFromBasePoint
or during GetPoint by entering a number.
