This class visualizes the snapping of a moved object (target) to a
SnapLine (target line)
that has a fixed
distance to a non-moved object (source).
The source line is the line induced by the source to which the target shall keep the fixed distance.
The
sourceLineFrom and
sourceLineTo resp.
targetLineFrom and
targetLineTo positions mark significant segments of the source and target line for the
SnapResult at hand.
The fixed
distance can be visualized by a line between
distanceIndicatorFrom
and
distanceIndicatorTo which is orthogonal to the source and target lines.
This paintable draws a line between
sourceLineFrom and
sourceLineTo as well as a
double-pointed arrow between
distanceIndicatorFrom and
distanceIndicatorTo.
The source point is further marked with a cross.
