- Added support for hiding model arrays in the rendering pipeline to optimize performance during VR gameplay. - Introduced new functions in `gx_model_visibility` to manage hidden model arrays and their visibility based on game state. - Enhanced cockpit recentering logic to ensure accurate seat measurements and eye positioning during gameplay. - Updated `FirstPersonState` to track cockpit height and forward direction, improving VR experience. - Added tests for Bullet Bill model visibility and cockpit height adjustments to ensure functionality and stability. - Refactored existing code to accommodate new features and improve overall code organization.
