This includes a small change to our custom material task because old
gradle passed only the contents of out-of-date directories, newer gradle
passes both the contents and the directory itself.
* Fix the Android filamesh file loader
The loader was not updated to support the SNORM16 format now sometimes
used to encode UV sets in filamesh files.
Fixes#708
* Update android/samples/image-based-lighting/app/src/main/java/com/google/android/filament/ibl/MeshLoader.kt
This change also optimizes the size of existing images using squoosh.app.
This should make the main README a lot lighter and faster to load (it saves
several MiBs).
This change will allow the skybox use a compressed texture format.
For now, the old internal format "RGBM" is still honored, but in a
forthcoming change we will replace the enum with UNUSED.
