The WorldInfo class represents the state of an instance in the "world" (i.e. the Layout it is in). This includes information like its position, size, angle, Z order, layer and so on.
Only "world" type plugin instances have an associated WorldInfo. It is typically obtained by using the Instance GetWorldInfo() method.
For performance reasons, changing the X, Y, angle, width, height or origin does not update the corresponding bounding box, which is stored separately. If any of these properties are changed, you must call SetBboxChanged() afterwards to ensure the runtime re-calculates the bounding box.
