- Moved background rendering functionality from the editor to a dedicated GUI module, enhancing modularity and separation of concerns. - Introduced layout helpers for consistent theme-aware sizing across the GUI, improving UI consistency and maintainability. - Updated CMake configuration to reflect the new structure, ensuring proper linkage of the background renderer and layout helpers. Benefits: - Improved organization of GUI components, facilitating easier updates and enhancements. - Enhanced user interface consistency through theme-aware layout management.
