 - Use both `mesh.visibility` and `material.alpha` values to compute the global alpha value used by the soft transparent shadow rendering code. Formerly was only using `mesh.visibility` ([Popov72](https://github.com/Popov72))
-- The `Texture.hasAlpha` property is automatically set by the KTX2 loader if the texture has an alpha channel ([Popov72](https://github.com/Popov72))
 - Depth renderer: don't render mesh if `infiniteDistance = true` or if `material.disableDepthWrite = true` ([Popov72](https://github.com/Popov72))
