TurtleThread now uses the `TNavigator` class from the builtin `turtle.py` module to handle navigation (but copying the source code instead of importing to ensure compatibility with systems without TKinter).
**Note:** Before this release, TurtleThread used the same coordinate system as TurtleStitch, which has a flipped y-axis compared to `turtle.py`. You may therefore observe that your patterns are flipped compared to the previous version.
