Add scrollpanel widget

Browse Source 
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.
