Bug: Light Cookie Textures are off by 90° counterclockwise

[KrisCatboy]

Describe the bug

as it says in the title. compared to an env_projected_texture, light_rt_spot's projection is sideways with the same angles.

To Reproduce

1. download and extract the provided map
2. load it up in-game with map light_cookie_issue
3. have a look

Issue Map

light_cookie_issue.zip
i made the map in p2ce, but used generic textures so it should load in other strata games too

Expected Behavior

light_rt_spots and env_projectedtextures of the exact same angles should project their cookies/textures the exact same way

Operating System

Arch Linux
