Owner

The previous support for GLTF was pretty primitive, it only supported loading meshes, and didn't load texture samplers. This pr fixes a lot of those, these improvements enabled the Sponza scene (gltf optimized) to load with no issues related to loading.

(ignore missing AA and issues with transparent textures, they require improvements to the renderer)

Improvements:

GLTF Scene loading
GLTF scene node hierarchy
Retrieve the world transforms of scene nodes and use them in the renderer
Fix a bug with the renderer transform buffers caused by only allowing a single transform per entity. (commit)
Load the texture sampler of the GLTF texture and use it inside the renderer.

ecs: fix World::insert, finish a TODO related to it

The TODO was that if the archetype has a single entity, add a component column for the new component instead of moving the entity to a brand new archetype

Create a new crate! lyra-scene for representing a SceneGraph in an ECS world

Some cleanup

scene: some cleanup

resource: improve gltf loader to show scene hierarchy and node local transform

fd2b1683cc

resource: load multiple gltf scenes

b3105bc668

ecs: fix filters

resource: Create Gltf object, expand GltfScene to collect all node transforms, other qol changes

render: process GltfScenes and Node local transforms

8d1961bb08

render: fix the TransformBuffers that could only store a single Transform for an entity

This caused Scenes to be rendered poorly since all meshes would use the Transform of the last processed mesh

cleanup some simple compiler warnings

resource, render: load in texture sampler from gltf and use them in the renderer
