    Introduced default values for size and height to simplify
initialization.
    Replaced deprecated mesh operations with TranslateModifier and
RotateModifier for cone transformations.
    Modularized rendering logic by introducing renderMesh to reduce
redundancy and improve readability.
    Centralized cone creation logic in createCone for better code reuse
and consistency.
    Enhanced method and variable naming for clarity.

- Updated class name from `ViewGizmo` to `ViewportCompass` to better
reflect its purpose as a non-interactive orientation indicator for the
viewport.
- Adjusted references and comments to align with the new name.

- Switched to `Vector3f` for cleaner rotation handling.
- Centralized rotation updates using `setRotation(Vector3f)` with
clamping logic to ensure safe ranges (-π, π).
- Removed individual axis setter methods for simplicity and better
maintainability.

- Documented the purpose of the `ViewportCompass` class.
- Added JavaDoc for all methods to explain their purpose, parameters,
and logic.
- Improved maintainability and developer clarity by providing context
for each helper method and transformations.

- Restructured package hierarchy to better organize framework
components.
- Decoupled core UI logic from Processing-specific implementations,
paving the way for broader flexibility and rendering backends.
- Began transforming library from a prototype to a robust, extensible UI
framework.
  - Introduced abstract base classes and interfaces for key components.
  - Updated existing components to align with the new architecture.
- Enhanced modularity by improving separation of concerns:
  - Moved rendering logic to dedicated `Renderer` classes.
- Improved code clarity and maintainability with better encapsulation
and naming conventions.
- Added comprehensive JavaDocs to foundational classes for improved
readability and usability.

This commit marks the foundational shift from a prototype to a polished
framework capable of supporting future scalability and flexibility.
Follow-up commits will address integration, performance tuning, and
additional feature development.

- Introduced `Light` interface to define common properties and behavior
for all light types.
- Added `LightRenderer` interface to decouple rendering logic for
different light types.
- Implemented `DirectionalLight` for uniform parallel lighting,
typically used for simulating sunlight.
- Implemented `PointLight` for omnidirectional light sources.
- Implemented `Spotlight` for directional lighting with limited cone
angles.
- Added `LightType` enum to categorize and identify light types.

This commit establishes a flexible and extensible lighting system,
enabling dynamic light management and rendering in the scene graph.
