add some more pipelined-rendering shader examples (#3041) based on #3031 Adds some examples showing of how to use the new pipelined rendering for custom shaders. - a minimal shader example which doesn't use render assets - the same but using glsl - an example showing how to render instanced data - a shader which uses the seconds since startup to animate some textures Instancing shader: ![grafik](https://user-images.githubusercontent.com/22177966/139299294-e176b62a-53d1-4287-9a66-02fb55affc02.png) Animated shader: ![animate_shader](https://user-images.githubusercontent.com/22177966/139299718-2940c0f3-8480-4ee0-98d7-b6ba40dc1472.gif) (the gif makes it look a bit ugly) Co-authored-by: Carter Anderson <mcanders1@gmail.com>

#version 450
Update shader_material_glsl example to include texture sampling (#5215) # Objective Add texture sampling to the GLSL shader example, as naga does not support the commonly used sampler2d type. Fixes #5059 ## Solution - Align the shader_material_glsl example behaviour with the shader_material example, as the later includes texture sampling. - Update the GLSL shader to do texture sampling the way naga supports it, and document the way naga does not support it. ## Changelog - The shader_material_glsl example has been updated to demonstrate texture sampling using the GLSL shading language.

Swap material and mesh bind groups (#10485) # Objective - Materials should be a more frequent rebind then meshes (due to being able to use a single vertex buffer, such as in #10164) and therefore should be in a higher bind group. --- ## Changelog - For 2d and 3d mesh/material setups (but not UI materials, or other rendering setups such as gizmos, sprites, or text), mesh data is now in bind group 1, and material data is now in bind group 2, which is swapped from how they were before. ## Migration Guide - Custom 2d and 3d mesh/material shaders should now use bind group 2 `@group(2) @binding(x)` for their bound resources, instead of bind group 1. - Many internal pieces of rendering code have changed so that mesh data is now in bind group 1, and material data is now in bind group 2. Semi-custom rendering setups (that don't use the Material or Material2d APIs) should adapt to these changes.

improve shader import model (#5703) # Objective operate on naga IR directly to improve handling of shader modules. - give codespan reporting into imported modules - allow glsl to be used from wgsl and vice-versa the ultimate objective is to make it possible to - provide user hooks for core shader functions (to modify light behaviour within the standard pbr pipeline, for example) - make automatic binding slot allocation possible but ... since this is already big, adds some value and (i think) is at feature parity with the existing code, i wanted to push this now. ## Solution i made a crate called naga_oil (https://github.com/robtfm/naga_oil - unpublished for now, could be part of bevy) which manages modules by - building each module independantly to naga IR - creating "header" files for each supported language, which are used to build dependent modules/shaders - make final shaders by combining the shader IR with the IR for imported modules then integrated this into bevy, replacing some of the existing shader processing stuff. also reworked examples to reflect this. ## Migration Guide shaders that don't use `#import` directives should work without changes. the most notable user-facing difference is that imported functions/variables/etc need to be qualified at point of use, and there's no "leakage" of visible stuff into your shader scope from the imports of your imports, so if you used things imported by your imports, you now need to import them directly and qualify them. the current strategy of including/'spreading' `mesh_vertex_output` directly into a struct doesn't work any more, so these need to be modified as per the examples (e.g. color_material.wgsl, or many others). mesh data is assumed to be in bindgroup 2 by default, if mesh data is bound into bindgroup 1 instead then the shader def `MESH_BINDGROUP_1` needs to be added to the pipeline shader_defs.

// o_Target = PbrFuncs::tone_mapping(Color * texture(sampler2D(CustomMaterial_texture,CustomMaterial_sampler), v_Uv));
Improve shader_material example (#10547) # Objective - The current shader code is misleading since it makes it look like a struct is passed to the bind group 0 but in reality only the color is passed. They just happen to have the exact same memory layout so wgsl doesn't complain and it works. - The struct is defined after the `impl Material` block which is backwards from pretty much every other usage of the `impl` block in bevy. ## Solution - Remove the unnecessary struct in the shader - move the impl block
