/// Each is based on the premise that if a point is behind the real world, it has intersected with it (except when
/// using realworldthickness). This is especially when checked each frame on a moving object, like a projectile.
/// In each function, "countinvalidascollision" specifies if off-screen pixels or missing depth values should count as collisions.
/// "realworldthickness" specifies how far back a point needs to be behind the real world before it's not considered a collision.

/// Checks an individual point in world space to see if it's occluded by the real world.
