The refactor includes: - Modifying method signatures in classes like `AnimationScenario`, `Images`, `DrawingArea`, `AttributeView`, `Snake`, and others. - Removing the parameterless `OnDrawingContent` method from the `View` class. - Updating calls to the base class implementation to pass the `context` parameter. - Adjusting comments and documentation to reflect the new method signature. This change ensures consistency and prepares the codebase for more advanced drawing capabilities.
