- More sky changes: Textures taller than 200 pixels but shorter than 241

are scaled to the height of a 200 pixel tall sky. Skies taller than 240
  use the same scale as a 240 tall sky but are shifted down to make the
  top of the texture align with the top of the screen when looking fully up.
  Thus, by using a sky texture with a height of 240 or more pixels, the sky
  will be drawn with square pixels instead of the vertically elongated ones
  imposed by Doom's native 320x200 resolution.
