Map option to extend the sky hack to lower textures

[Da Spadger]

The issue in a nutshell: https://i.imgur.com/6IxSbDZ.png

The two floors with F_SKY1 don't connect through the lower texture the way the ceilings do with the upper texture, which is how the sky hack has always worked. Some way of enabling it to work on the lower texture as well would be great. I'm unsure on what the best way of implementing it would be; maybe as a MAPINFO option.

Doesn't it work if you keep the lower texture empty?

... So it does.

Nevermind.

EDIT: Oh, actually there's an issue with that. If your viewpoint height is below the higher floor, it makes a HOM. https://i.imgur.com/50rJ5iy.png
