Thomas Lemaire 5b76a31485 fix trivial warnings
mainly unused parameter and unused function
some parameters are indeed used in a debug built, I used the
(void)(param) trick

Approximate specularity / glossiness in metallicRoughness materials
Before, models (of traditional lighting models) with specularity/glossiness would be completely flat when exported to metallicRoughness. These changes approximate glossiness (as an inverse of roughness, with specular intensity as a multiplier) both reading from gltf2 and writing to gltf2.

SpecularFactor import and export improvements
The changes here (which only apply to reading from or writing to pbrSpecularGlossiness) will:

- store and read specular color on `AI_MATKEY_COLOR_SPECULAR ` rather than `AI_MATKEY_GLTF_PBRSPECULARGLOSSINESS_SPECULAR_FACTOR`
- store and read specular texture from `aiTextureType_SPECULAR` rather than `AI_MATKEY_GLTF_PBRSPECULARGLOSSINESS_SPECULARGLOSSINESS_TEXTURE`. Even though pbrSG’s specularGlossiness texture uses the alpha channel for glossiness, it will still work well enough with just the RGB channels of the image

Diffuse color and diffuse texture import and export improvements
These changes do a better of importing and exporting baseColor colors and textures, as well as diffuse colors and textures (in the case of pbrSpecularGlossiness)

- baseColorFactor will be stored on both `$clr.diffuse` and `$mat.gltf.pbrMetallicRoughness.baseColorFactor`, and will be extracted from `$mat.gltf.pbrMetallicRoughness.baseColorFactor` first, and falling back to `$clr.diffuse`. The behaviour for baseColorTexture is similar
- pbrSG’s diffuseFactor will now only be store on `$clr.diffuse` (overwriting any previous assignments to `$clr.diffuse`, e.g. from metallicRoughness’ baseColorFactor, as diffuseFactor is more analogous to diffuse color than baseColor), and will only extract from `$clr.diffuse`

Fix alphaMode storage and reading
alphaMode is now converted from a std::string to an aiString and back to std::string, since aiString is easier to store and retrieve from aiMaterial properties than std::string

Fixes issues of alphaMode being written out as `\fOPAQUE\0\0\0\0\0\0…`

Revert "store node mesh vs. meshes"

Jeremy Cowles c207e74534 Fix glTF 2.0 multi-primitive support
Previously, only one primitive was supported, in fact memory was corrupted
when more than one primitive was found per glTF mesh.

In this change, each primitive is unrolled as a new Assimp Mesh, resulting
in multiple Assimp meshes per node when multiple primitives exist per
glTF mesh. This is required in the general case, since glTF primitives can
have different material bindings and primitive modes.

Remove KHR_binary_glTF code
Binary glTF is now part of the glTF2 spec. However, it’s implemented incorrectly, so will be temporarily removed

Sampler improvements; Add new LazyDict method
Samplers are now imported into assimp internal format from textures;
Samplers have defaults as per spec;
Sampler enums are strongly typed with UNSET values;
Samplers are exported properly;
Sampler filters are exported as well;
Samplers are re-used across textures on export
Default sampler values are not written
