ASTC 12x12 working in webgl. Looks awful and not even sure it's useful, but the data size for an arrayed atlas with two pages + a regular texture is roughly 20kb.

Currently working on rewriting our @defold.com texture compression pipeline to support more hardware texture formats such as ASTC and WebP via plugins. This is the current progress, we can now pick up and install compressor plugins that compresses each mipmap individually! #gamedev
