Research direction
Locate all usages of createImageBitmap in the CesiumJS source code. Investigate the current deprecation warning and identify the recommended replacement API (e.g., using ImageBitmapOptions or a different approach). Ensure cross browser compatibility and update the code accordingly. Consider adding a polyfill or fallback if needed. Test the changes thoroughly.
