// Description : This funny bounding volume is an infinite line with
|
|
// no thickness and extending to infinity in both
|
|
// directions.
|
|
//
|
|
// Note that it *always* extends in both directions,
|
|
// despite the fact that you specify two points to the
|
|
// constructor. These are not endpoints, they are two
|
|
// arbitrary points on the line.
