[Encoding/compression] Lightmap Encoding Quality settings do not apply to Shadowmask textures

Progressive Lightmapper


Steps to reproduce:

1. Download and open the attached project
2. Open SampleScene
3. Bake the lighting
4. Navigate to Project Settings > Player > Lightmap Encoding Quality and make sure that it is set to High
5. Select shadowmask texture
6. Notice that its compression quality is set to Normal


- Reproduces on 2017.4.38f1, 2018.4.20f1, 2019.3.6f1
- This negatively impacts the quality of shadowmask output (please see the attached .gif)

  1. Resolution Note (fix version 2022.1):

    The behavior that Lightmap Encoding doesn't affect shadowmask textures is actually by design (albeit arguably a confusing design). Lightmap Encoding was originally intended to only affect reguar lightmaps and directional lightmaps, but only in some cases. This is not intuitive and we aim to address this issue by completely decoupling Lightmap Encoding from lightmap compression. Instead, we aim to add a new explicit lightmap compression setting in the Lighting Data Asset that gives the user full control of the compression quality used for _all_ lightmaps (including directional lightmaps, and shadowmasks). This removes a lot of edge case and simplifies the logic regarding how to configure lightmap compression.
