In preparation for [The Unholy Society](https://unholy-society.com/) on iOS…

1. Packaging of textures [specific to given platform](https://castle-engine.io/creating_data_auto_generated_textures.php) by the [build tool](https://github.com/castle-engine/castle-engine/wiki/Build-Tool) has been fixed, to really package only textures useful on given platform.

2. The [build tool](https://github.com/castle-engine/castle-engine/wiki/Build-Tool) `auto-generate-clean` subcommand was improved: by default it cleans only unused files in the `auto_generated` subdirectories. Call the `castle-engine auto-generate-clean --all` to clean all current auto-generated files.

3. [Vibrations on iOS](https://github.com/castle-engine/castle-engine/blob/master/tools/build-tool/data/ios/services/vibrate/README.md) now work.
