91ff1d87eb Replace prebuilt KTX with a build step. 
This removes the samples/envs folder and replaces these KTX files with a
build step that is driven by CMake / gradle / bash, depending on
platform.

This makes it easier to use IBL files that are generated by the latest
and greatest version of cmake.

ce4a3edf7b gltf_baker: visualizers now use fp32 textures. 
This allows us to skip the CPU-side vector-to-color conversion that
occured at the end, and makes the real-time visualization consistent
with the final visualization.

Parameterization can run into problems for very large, very small, or
off-center assets. Showingthe min/max helps users diagnose these issues.

cbfb364c41 Introduce libs/rays and implement AO baking. 
The AO baking procedure consists of the following steps:

1. Flatten the glTF hierarchy.
2. Generate a single 2D parameterization for the entire scene.
3. Embree Pass 1: Create G-Buffer using the above UVs as vert positions.
4. Embree Pass 2: Cast rays from the positions embedded in the G-Buffer.

The `gltf_baker` tool is not ready for general use but already
produces reasonable results for certain well-formed models.
