Non-stretched skies are still stretched

[Chris]

Although turning off Stretch Short Skies does shrink short skies, it still comes out more stretched than it should. Here are two comparative screenshots, one with ZDoom, the other with GZDoom, both with Stretch Short Skies turned off. Obviously I wouldn't expect GZDoom to be able to duplicate the sky exactly, but it still seems a bit extreme, to me..

Also, it seems the sky is set a bit higher than normal, because there are places where I can clearly see the sky wrap underneath itself in the original levels, where I can't in ZDoom.

I changed the scaling but I can't do much about the rest. The sky rendering method is too different to get it to match properly in all cases. I tweaked it a bit so I hope it's better now.
