[UNSURE] Can't place doors/Windows close together (ALT)

I was asked just to explain what is happening here since I have experience making buildmode items, and it's not actually a bug. It is just how it was done to implement this feature while still obeying how windows and their cutout work. 

Each window has an equivalent cutout and equivalent resource for it's size. So say we have a 2 tile window, it has a cutout that says it is 2 tiles and cuts out the wall for it among other things. The cutout must be the only one on that 2 tiles it is placed since multiple cutouts cannot be overlapped. That is just a limit of the system in place.

Now in comes the patch. We can now move 1/32 of a tile with alt or now default 1/2 tile or 1/4 tile with F5. Although we have this more flexible movement and placement, the rule that a cutout cannot occupy the same space still applies. In this case we much look at a full tile when moving the windows over. Cutouts still cannot be applied to a half tile after the patch because that would imply 2 cutouts being applied to the same tile space. This is just not possible, even with the update. So in a lot of the examples I have seen, people are trying to place more then 1 window over a single tile causing the issues. This is just a limitation of how windows and cutouts are coded into the game engine, not a bug. This is how I understand it from my perspective. 

Simply put, windows and their cutout cannot occupy the same tile, even with the new 1/32 tile placement. If 2 windows occupy a single tile at the same time, the cutouts wont work properly.
