ImageUtils: Remove usage of OffscreenCanvas in .getDataURL()

OBJLoader2 V2.4.2: Generic error callback + align load and loadMtl callbacks

Improve offscreencanvas example for cross-browser inter operability

Unreal Bloom Example: cleanup

#14606: `OBJLoader2` allows to register a generic error handler. If this callback is available it will be used instead of a throw. `LoaderWorkerDirector` uses this callback to report a problem, but continue with the next loading task.
`OBJLoader2.loadMtl` now allows to pass onProgress and onError as well.

Examples: Avoid new when calling lookAt()
