Purple Sunset Horizon by Martini

Description
This horizon uses over 16 texture pages and might not work well depending on how optimized your WAD is. The bottom part
could be optimized more and stripped of some textures if you want to. I just no longer have the source textures and it shouldn't be too much of an issue.

Horizon is compatible with the Skylayer= settings if you wish to use those.
