Compatibility mode

[TinyTakinTeller]

This seems like an awesome plugin/addon, but... I have one worry.

Proposition
Is it possible to avoid use of .gdshader and to rewrite the functionality? (Optionally as a compatibility mode toggle?)

Notes
Shaders are generally a big can of worms that can be very useful but also very problematic.

• They are often problematic in web exports
  • for example crashes on macOS platforms: Blur shader doesn't work in WebGL 2.0 godotengine/godot#91717
    • report in wild: https://itch.io/t/3991626/game-completely-freezes-when-i-click-on-darkness-macos-brave
• They often cause inconsistencies, for example cache-lag when first time entering scene or being modified.
  • Shader compilation
    • Compatibility renderer shader compilation very slow in Compatibility renderer godotengine/godot#86731
    • Workarounds https://www.youtube.com/watch?v=oG-H-IfXUqI&t=438s

Use case
A minimalistic web game where unnecessary complexity (e.g. shaders) is sacrificed for compatibility and stability.

Hey,
I understand the problem and to be honest, had no idea there is such a big problem with gdshaders in optimization department. So thank you for that.
About the 'compatibility mode toggle' feature proposition, I love web games and will implement this feature for sure but, we can use the gdshader to render every frame of the transitions on development time and save them all as sprites to then use them in an animated sprite node to replicate almost the same behavior as we have in gdshader but...
The problem is that I already promised to some developers to fix the problems they proposed in this repository on discussions and issues sections and never went back on them to keep my word due to lack of having extra time and a proper time management of my life.
So I said all that to deliver the message of "I will fix it, but when? I don't know... hopefully in 3 to 4 months in the future".
Thanks for the issue, I'm really happy people are using this and still care about it enough to issue even though I'm not putting enough time on this project. 🙏
