Split mesh shader files (#4867) # Objective - Split PBR and 2D mesh shaders into types and bindings to prepare the shaders to be more reusable. - See #3969 for details. I'm doing this in multiple steps to make review easier. --- ## Changelog - Changed: 2D and PBR mesh shaders are now split into types and bindings, the following shader imports are available: `bevy_pbr::mesh_view_types`, `bevy_pbr::mesh_view_bindings`, `bevy_pbr::mesh_types`, `bevy_pbr::mesh_bindings`, `bevy_sprite::mesh2d_view_types`, `bevy_sprite::mesh2d_view_bindings`, `bevy_sprite::mesh2d_types`, `bevy_sprite::mesh2d_bindings` ## Migration Guide - In shaders for 3D meshes: - `#import bevy_pbr::mesh_view_bind_group` -> `#import bevy_pbr::mesh_view_bindings` - `#import bevy_pbr::mesh_struct` -> `#import bevy_pbr::mesh_types` - NOTE: If you are using the mesh bind group at bind group index 2, you can remove those binding statements in your shader and just use `#import bevy_pbr::mesh_bindings` which itself imports the mesh types needed for the bindings. - In shaders for 2D meshes: - `#import bevy_sprite::mesh2d_view_bind_group` -> `#import bevy_sprite::mesh2d_view_bindings` - `#import bevy_sprite::mesh2d_struct` -> `#import bevy_sprite::mesh2d_types` - NOTE: If you are using the mesh2d bind group at bind group index 2, you can remove those binding statements in your shader and just use `#import bevy_sprite::mesh2d_bindings` which itself imports the mesh2d types needed for the bindings.

#define_import_path bevy_pbr::pbr_bindings
update shader imports (#10180) # Objective - bump naga_oil to 0.10 - update shader imports to use rusty syntax ## Migration Guide naga_oil 0.10 reworks the import mechanism to support more syntax to make it more rusty, and test for item use before importing to determine which imports are modules and which are items, which allows: - use rust-style imports ``` #import bevy_pbr::{ pbr_functions::{alpha_discard as discard, apply_pbr_lighting}, mesh_bindings, } ``` - import partial paths: ``` #import part::of::path ... path::remainder::function(); ``` which will call to `part::of::path::remainder::function` - use fully qualified paths without importing: ``` // #import bevy_pbr::pbr_functions bevy_pbr::pbr_functions::pbr() ``` - use imported items without qualifying ``` #import bevy_pbr::pbr_functions::pbr // for backwards compatibility the old style is still supported: // #import bevy_pbr::pbr_functions pbr ... pbr() ``` - allows most imported items to end with `_` and numbers (naga_oil#30). still doesn't allow struct members to end with `_` or numbers but it's progress. - the vast majority of existing shader code will work without changes, but will emit "deprecated" warnings for old-style imports. these can be suppressed with the `allow-deprecated` feature. - partly breaks overrides (as far as i'm aware nobody uses these yet) - now overrides will only be applied if the overriding module is added as an additional import in the arguments to `Composer::make_naga_module` or `Composer::add_composable_module`. this is necessary to support determining whether imports are modules or items.

Use a single line for of large binding lists (#9849) # Objective - When adding/removing bindings in large binding lists, git would generate very difficult-to-read diffs ## Solution - Move the `@group(X) @binding(Y)` into the same line as the binding type declaration
