native2tex

This PoC demonstrates sharing a ByteArray between:

• JavaScript
• Java/Kotlin
• C/C++/Rust

The hope is that if that ByteArray/Uint8Array backs a WebGL texture, changes to it can be efficiently rendered from native code into the Android WebView.

Update

This PoC Failed: it's just not possible to pass binary data from Java to JavaScript
