CommonLua/Core/ProceduralMeshShaders.lua

---
--- Initializes the ProceduralMeshShaders table and provides a function to register new procedural mesh shaders.
---
--- The `InsertProceduralMeshShaders` function takes a table of shader definitions and registers them in the `ProceduralMeshShaders` table.
--- Each shader definition is a table with the following fields:
---
--- - `shaderid`: The ID of the shader file to use.
--- - `defines`: A table of preprocessor defines to apply to the shader.
--- - `name`: The unique name to identify the shader.
--- - `topology`: The primitive topology to use for the mesh.
--- - `cull_mode`: The culling mode to use for the mesh.
--- - `blend_mode`: The blend mode to use for the mesh.
--- - `depth_test`: The depth testing mode to use for the mesh.
--- - `pass_type`: The pass type for the shader (optional).
---
--- The `RegisterProceduralMeshRules` function is called to register the new shaders with the rendering system.
