glsl compile error with GLSL ES 3.00 about engine HOT 4 CLOSED

current compile workflow:

will case some problom:

• glsl300 -> webgl1.0 will cause error
• glsl300 -> webgl2.0 will cause error in some grammar

maybe the final solution?

@zhuxudong @Sway007 I think WebGPU should also be taken into consideration. This is the way to ensure that our architecture is future-proof.

flowchart LR
shaderLab --> AST{AST Compile};
AST --WebGL2--> GLSL300;
AST --WebGL1--> GLSL100;
AST --WebGPU--> WGSL;

@zhuxudong For now, you just need to apply a quick patch.

yes，the source of the AST is not only the shaderLab, such as you original glsl100 or glsl300 or wgsl, I don't know if we should consider this

I think choosing to establish a standard language is a better option. It makes no sense to support such a wide array of syntaxes. These languages should serve as compiled outputs, rather than inputs.
