v0.2.0 - Improved Materials

Released 2021-10-09

This release saw a signifigant amount of cpu side optimization.
In a 50k object scene, the render loop went from taking 16ms to taking 1.75ms, a 9x speedup

Added

• rend3: Added an explicit dependency on wgpu-core and wgpu-hal to ensure bug-fixes are included.
• rend3-gltf: Add the ability to turn off image's default features.
• rend3-gltf: Add support for ktx2 and dds images.
• rend3-gltf: Expose implementation functions
• rend3-pbr-bake: Added crate for automatic light baking to a texture.

Changed

• rend3: IMPORTANT: You now must call output.present() in order for things to show up on screen.
• rend3: Material is now a trait and render routines can specify their own material.
  • rend3::types::Material is now rend3_pbr::material::PbrMaterial
  • Renderer::update_material no longer takes a MaterialChange, it takes a completely new material.
• rend3: renderlists refactored to have a generic Input and Output.
  • Renderer::renderer passes through the Input and Output.
  • OutputFrame is now a user-side only utility.
• rend3: AddTexture* will now create/upload the texture before the call returns.
• rend3: ResourceHandle now prints the actual reference count while debug printing.
• rend3: CameraProjection now deals with view matrix, instead of location/yaw/pitch @scoopr
• rend3: Update to glam 0.19 @scoopr
• rend3 & rend3-gltf: update to wgpu 0.11
• rend3-pbr: Input is of type () and Output is type &TextureView.
• rend3-gltf: Added labels to all the different data types.
• rend3-gltf: Errors now use a SsoString instead of a String for the URI.
• rend3-gltf: All implementation functions no longer write into a single &mut LoadedGltfScene, but return their results directly.

Fixed

• rend3: No longer require pipeline rebuilds when bind group length updates.
• rend3-pbr: fix rendering of cutout objects in shadow passes.
• rend3-pbr: remove redundant material changes in cpu mode.
