In placement, we use two methods to update the bounding box: the 3D bounding box (also used for 2D architecture) and the per-layer bounding box. When a swap happens, multiple variables are updated, indicated by the ts (temporary swap) prefix. We can put all these variables into a class. Since only a subset is used depending on the bounding box type, you can examine how these variables are updated throughout the file and write methods for this class to update the appropriate ones.
After some discussion, it was decided to not use inheritance or the type eraser due to potential performance degradation and the lack of readability. In this PR, the control flow that decides 3d or 2d placement are wrapped into a class.
