GLTFLoader: Use ImageBitmapLoader in for Safari >= 17.

[paugit]

Description

Start using ImageBitmapLoader for Safari >= 17 to fix texture loading in a web worker. Also makes Safari three.js texture loading performance better.

Note

I have only tested this on Safari 17.5 as I don't have older one available. Partial support for CreateImageBitmap in Safari has been around for a longer time but it would be great if someone could make sure that textures still load fine with GLTFLoader when using Safari 17.0. If not, we can change the version limit to 17.5.

The currently used TextureLoader cannot be used in a web-worker and will fail with an error.

I've tested the PR but only with 17.5.

If not, we can change the version limit to 17.5.

If no other dev tests this PR with version 17, let's use 17.5 to be on the safe side.

I only have access to 17.5 as well, it works there for me. Is it possible to install older Safari versions without reinstalling macOS?

Works on 17.4.1

Is it possible to install older Safari versions without reinstalling macOS?

AFAIK, WebKit is separated from Safari and part of macOS so it is available for other apps as well. If you upgrade macOS, you automatically upgrade Safari so it is in sync with the OS's WebKit version. A browser downgrade isn't possible.

It's probably easiest to find out whether this PR works with Safari versions in the range 17.0 - 17.4.1 when we deploy it in production (especially since no one responded here https://x.com/threejs/status/1800474140752896478).

If we encounter any issues, a fix or revert should be easily done.
