- use resgen to package the DFG LUT into filament, instead of using
a large include of a C array.
- add a zstd compression step, which reduces the size from ~100KB to
~75KB.
The overhead of zstd is about 90KB uncompressed, however it will pay
for itself tenfold when we use it to compress material packages.
- Ensure C++17 is used to compile sample projects
- Upgrade to the latest Xcodegen and re-generate projects
- Add a bundle ID disambiguator so users don't need create unique bundle Ids when opening sample projects
- Add a simple generate-samples.sh script
* Add multi-scene support to gltf_viewer.
To test this, I generated a multi-scene asset as follows.
```
gltf-transform merge Avocado/glTF/Avocado.gltf \
BarramundiFish/glTF/BarramundiFish.gltf \
~/Desktop/Merged.gltf
```
* Specify c++17 in pbxproj files.
