- Introduce `drawAssetCentered` method in `dynamicimages_image_t` for drawing assets visually centered on specified coordinates. - Reset virtual canvas/page after image rotation in both `dynamicimages_asset_t` and `dynamicimages_image_t` to ensure consistent positioning. - Update `machine_1` logic to use `drawAssetCentered` for improved thumb drawing and dynamic pivot alignment. - Adjust thumb rotation calculations and positioning logic for better visual rendering.
