# Description of Changes
This pull request includes several updates to the Docker configuration
and Java application UI scaling. The changes enhance environment
variable management, dependency installation, and UI responsiveness to
different screen sizes.
### Docker Configuration Updates:
* Added new environment variables `STIRLING_PDF_DESKTOP_UI`,
`PYTHONPATH`, `UNO_PATH`, and `URE_BOOTSTRAP` to `Dockerfile` and
`Dockerfile.fat` to improve the configuration and integration of the
LibreOffice environment.

* Updated the `CMD` instruction in `Dockerfile` and `Dockerfile.fat` to
run both the Java application and `unoserver` simultaneously.

dependencies and setup a virtual environment.

### Workflow Enhancements:
* Added `STIRLING_PDF_DESKTOP_UI` environment variable to the GitHub
Actions workflows (`PR-Demo-Comment.yml` and `push-docker.yml`) to
ensure consistent environment settings.

### Java Application UI Scaling:
* Introduced `UIScaling` utility to dynamically adjust the size of UI
components based on screen resolution in `DesktopBrowser` and
`LoadingWindow` classes.

better visual quality.
