Add option to toggle GLSL preprocess

[06wj]

Added a switch for shader preprocess, making it easier to understand the shader and get rid of any unnecessary distractions.

• Test demo: https://hilo3d.js.org/examples/geometry_box.html

• The builded extensions for test
  extensions.zip

• preprocess off:
  

• preprocess on:

I use @shaderfrog/glsl-parser to do the preprocess.It supports both GLSL 1.0 and GLSL 3.0.

@sebavan Is it possible to get the improved Spector.js from the Chrome Web Store?
The version currently registered in the Store seems to be 0.9.28 (2022-08-02).
