- Improved sky stretching a bit: It now only stretches the sky as tall as it needs to be: 228 pixels, not 256. It no longer stretches horizontally, either. The reason it stretches to 228 and not 200 pixels is because Doom shifted its sky texture down 28 pixels. By stretching to 228 pixels, we can keep the sky tiled at the same height on the horizon. Skies 200 pixels tall (or more) will continue to tile at the center of the screen when looking directly ahead. SVN r1976 (trunk)
