// Description : A special kind of CollisionHandler that does nothing
|
|
// except remember the CollisionEntries detected the
|
|
// last pass. This set of CollisionEntries may then be
|
|
// queried by the calling function. It's primarily
|
|
// useful when a simple intersection test is being made,
|
|
// e.g. for picking from the window.
