Edit and visualize irregular game panels for The Witness.

.NET Framework 4.7.2

1. Build TemplateGenerator and WitnessVisualizer
2. Run TemplateGenerator.exe to automatically generate some templates.
3. Run WitnessVisualizer.exe, open the templates and edit them.

Decorators mean some symbols that are shown on the puzzle's faces/edges/corners. If you want to add a new mechanic (thus need a new symbol) to the puzzles, you can create your own decorator. Two examples in this project are RingDecorator and CircleDecorator that do not belong to the original game.

1. Add and implement a new decorator class in PuzzleGraph\Decorators. See other implemented decorators for reference.
2. Add a XmlInclude(typeof(YourDecoratorClass)) attribute to PuzzleGraph\Decorator.cs so it can be (de-)serialized when saving/loading the puzzle.
3. Implement the rendering method of the decorator in WitnessVisualizer\PuzzleGraphRenderer.cs.
4. Add a new PuzzleToolkitDecoratorItem item in WitnessVisualizer\PuzzleToolkit.cs so that you can find one in the list view on the left of the editor.

1. PuzzleGraph provides a uniform graph structure for storing irregular game panels. It supports Serialization & Deserialization from XML.
2. MathHelper provides some basic analytical functions.
3. WitnessVisualizer implements the main editor form and the rendering functions.
4. TemplateGenerator is an ugly program to generate some common templates for The Witness puzzles.

1. WitnessVisualizer currently does not support adding/modifying graph nodes/edges/faces.
2. Hollow tetris will sometimes add random fragments due to unknown bugs of the WinForm drawing system.
