#### Shaders
- [`DEPTH_TEXTURE` now uses normalized device coordinates between `0.0` and `1.0` (inclusive) to match Vulkan behavior.](https://docs.godotengine.org/en/latest/tutorials/shaders/advanced_postprocessing.html#depth-texture)
- This requires modifying most shaders that rely on `DEPTH_TEXTURE` to make them still work as expected.
- Previously, coordinates would be between `-1.0` and `1.0` (inclusive) to match OpenGL behavior.
- Renamed the `.shader` file extension to `.gdshader`.
- Existing text-based shader files will have to be renamed before loading the project in a new engine version.
