KTX Textures look blocky from some angles/distance

[rsahlin]

From certain distance and/or angles a model with KTX textures look blocky. This is not due to compression artefacts since the model looks good in some other viewer for instance KTX textures are a mix of UASTC/ETC1S and are compressed using high quality.

Mid section looking blocky - perhaps no anisotropic filtering and issues with mip-levels and/or texture filtering?

The same model from a distance shows more blockiness - looks like filtering is not turned on and/or a mip-level problem.

This should fix the problem: https://github.com/ux3d/glTF-Sample-Viewer/tree/fix/KTX2_mipmap Will review with my team tomorrow.
