Synchronize multi object selection between Mastodon and Blender

[maarzt]

Currently only the active object in Blender gets synchronized with the focused object in Mastodon.

There is always only one active object in Blender and one focused object in Mastodon. But both Mastodon and Blender support to select multiple objects. This selection should be synchronized between Blender and Mastodon.

Challenges

Its hard to find a callback in Blender that is reliably triggered if the selection changes.

Acceptance criteria

• Changing the selection in Mastodon, updates the selection in Blender
• Changing the selection in Blender updates the selection in Mastodon
