// algorithm
// It's possible to walk through the closed door in room 448 and enter the crate
// room before act 5 due to differences in our pathfinding algorithm from Sierra's.
// Ego is able to stand one pixel farther than Sierra's algorithm allowed and
// reach the control area behind the door which triggers the room change.
// We work around this by expanding the closed door's polygon points by one
// pixel to prevent ego from being able to reach the control area.
// This edge case appears to be due to one of the door's points being one pixel
// within the room's walkable boundary, allowing ego to walk through this edge
// from certain positions. We work around this by moving the door's point by
// two pixels so that it's outside the room's walkable boundary.
//
// Applies to: All Floppy and CD versions
// Responsible method: transomDoor:createPoly
// Fixes bug: #9952
