The vertical door, seen in the BTS scenes throughout the single player campaign, and the Portal 1 style door, which unfortunately lacks some color details, and it still uses Portal 2 door sounds, because I couldn't find the Portal 1 versions in Portal 2 sounds.

Click to zoom.
(The Portal 1 wall texture was added in between of those doors to illustrate it fitting that style; it is not part of the door.)

The two new door types are simply added as ButtonType selections into Ben's existing door.

All the three different doors use the same icons in the editor...

In essence, it is, and looks better with holes cut into the walls around it, but it pretty much works as a 128x128 door.

Also, you should probably upload this to the 'Other Files' database, which automatically creates a thread and everything for it: downloads.php?cat=9

I did look up, but I did not find. Guess I was wrong, and will have to do that again.
Yes, the door is bigger than 128 units, but since you will probably put walls around the door anyway, it does not matter. There is a slight cosmetic error as the walls on the side of the door appear through the mechanisms of the door, but most people won't notice it unless they are particularly looking for such errors
Not sure how to cut holes in those walls...
