Environment Rework

[KivalEvan]

the long awaited environment rework is approaching

• complete environment and visual overhaul
• more environment + GLS environment added (still incomplete state but it work)
• environment removal/enhancement + animation now shown visually
• many lighting component/event rework
• event tracks definition change
• beatmap object visual update
• proper bloom fog + lighting + environment mirror
• custom Beat Saber shaders recreation
• move shader towards HLSL standard
• correctly parse custom color and info color scheme

this does not mean GLS lighting can be done yet, it will be the next step
if you wish to see environment in proper visual, do contribute on making an asset and shader better

final check to find any glaring issue that should be addressed before pushing to dev

known issue(s):

• missing assets on certain environment (a lot in GLS environment), you will see source engine missing texture
• shader/material inaccuracy is expected, do provide example where it does not seem as it should
• event light ID may be inaccurate or broken, please report if you find any and the actual light ID it supposed to light
• event placement may not work correctly, also please report
• spectrogram may not work on certain mesh/environment
• spectrogram is jittery on very high framerate
• heavy lighting environment is cpu taxing
