Changing Anisotropic level of a texture should not trigger a re-compression
How to reproduce:
1. Open the attached Aniso.zip project
2. Select Big texture in the Project window
3. Go to the Inspector window, set different Aniso level and press Apply
Expected: re-compression ios not trigger
Actual: re-compression starts
Reproducible with: 2018.4.26f1, 2020.1.1f, 2020.2.0a11
Note:
- From 2020.2.0a12 Anisotropic filtering is enabled for all textures in Quality Settings and the issue is not reproducible there

Resolution Note:
In Unity, a Texture (e.g., Texture2D) is both the sampler and texture. Hence, we need to reimport the texture when the sampler changes.
Two solutions are possible, both could be considered a feature request: separate the sampler from a Texture, or optimize the import pipeline such that texture sampler changes don't introduce full recompression.
This bug will be converted to a feature request.
