This PR introduces a new ScrollPanel component with the following capabilities: - Scroll Orientation Support: Allows scrolling in horizontal, vertical, or both directions, providing flexibility for different use cases. - Partial Object Rendering: Supports partial rendering of objects that are only partially visible within the scroll boundaries, improving visual accuracy and performance. - Boundary-Constrained Mouse Interaction: Handles mouse events strictly within the panel's visible boundaries, preventing interaction with objects outside the scrollable area. - Minimum Internal Size (min_width, min_height): Introduces support for virtual space management, allowing the panel to maintain a minimum internal size independent of its actual on-screen dimensions. Even when the panel is resized, this ensures that the content respects a defined virtual space (with min_width and min_height), effectively simulating a larger internal canvas. This is particularly useful for large content or scenarios where a more extensive scrollable area is required than the current visible panel.
