Move Adjustments before Tonemapping

[catboy-catfish]

I want to use the ACES tonemapper because of its realistic way of handling bright colors, but it adds too much contrast. Adjustments don't help, decreasing the contrast makes the image look washed out. This is because Adjustments comes after Tonemapping.

• Related to Add TonyMcMapface as a tonemapping mode (or allow using custom LUTs for tonemapping) #7263.

We can't change the default behavior to avoid breaking visuals in existing projects, but we could expose an Environment property to define the order in which operations are performed (from first to last):

• Tonemap > Adjustments > Color Correction (default, and the current behavior)
• Tonemap > Color Correction > Adjustments
• Adjustments > Tonemap > Color Correction
• Adjustments > Color Correction > Tonemap
• Color Correction > Tonemap > Adjustments
• Color Correction > Adjustments > Tonemap

You may be interested in AgX to avoid ACES' excessive contrast issues 🙂

The exposed Environment property looks good. I can get behind that.

AgX sounds like a decent alternative, but obviously that's not an easy thing to implement. Not sure if LUTs can perform realistic desaturation of brighter objects like this, but I don't know much about LUTs anyway.

I have a PR for it: godotengine/godot#87260

LUTs can do anything, including acting as a tonemapper if they are processed before tonemapping and you use Linear tonemapping in Environment.
