The QML profiler showed me that it was causing a *lot* of issues
when switching between extruders. More than 10% of the time in QML
was spent on just updating ine property in the workspace summary dialog.
There were other properties that were also being updated without there being a point.

In some situations this could cause a slowdown, since halfway through
calculating the values the extruder switch would happen. If this is
split up a bit, it's at least less noticeable

All the settings that are changed get a notification from the settingRelation.
There should be no need to re-fire all of those settings again!

This doesn't actually speed up the process, but it does give some indication
that something is going on while the changes are happening

This comes at some performance cost, sadly. This is necessary because the convex hull of every node may change if the transformation of any other node changes, since that transformation may adjust the total bounding box of the mesh group.

This is either the centre of the bounding box around all printable nodes in the scene, or the centre of the bounding box of the most-ancestral node that is not yet the scene root itself in one-at-a-time mode.

A small positive (>100) value is correct. It needs to compensate by increasing the size, usually. If you need to compensate by making it smaller, that means that the material would expand when cooling, which is very rare.

We have a change now that requires a version upgrade. This triggers all profiles to update for the user, and we must update accordingly in the built-in profiles.
Contributes to issue CURA-7118.
We're changing the unit of one of our settings, so we need to implement a version upgrade to change that for our users in case they changed this setting themselves.

So now if the model is grown due to shrinkage compensation, its collision area will also grow. This prevents objects adjacent to each other from hitting each other.
Contributes to issue CURA-7118.
We'll now actually compensate for the shrinkage. That means that the setting needs to become user-visible. We need to make that experience a bit more user-friendly.
The setting is now also global, with a resolve function. That means that the user can't change this per extruder any more, because the scale factor applied in the engine can only be global. The resolve function means that profiles can still apply a per-extruder value but this value gets resolved with other extruders' values.

If a cloud printer was connected, it would time out all the time. In some cases
it would do this in a single update loop (so connect and disconnect). Depending
on the machine of the user, this would either be visible or not at all.
This will now result in a job being put in the queue but not automatically printing, but there is at least a workaround for that.
Fixes Sentry issue CURA-14A.
