Updated voxel remesher defaults #97163

This is a minor to-do to create a smoother sculpting experience and freezes.

Issues

Preserve painted data

Often the user wants to preserve various object-data when remeshing. But by default the options to preserve "Painted Masks", "Face Sets" and "Color Attributes" are disabled.
Because of that these options need to be manually enabled for each new object that is created.
And all of these options combined will still perform better than just having the Fix Poles option enabled.

Since color attribute painting was recently introduced with D12587 it does make sense to update the defaults to preserve any painted data.

Fix Poles performance
The voxel remesher options that are currently enabled by default cause some issues.
By default the option "Fix Poles" is enabled, which leads to a lower vert-count when remeshing and cleaner topology.
This is a minor trad-off for the increased loading times, which can increase too much if more options to preserve additional object-data are enabled.
Here are some results after testing various combinations.

A monkey primitive with 536.769 vertices:

None options enabled = 1 second
Preserve Volume = 1 second
Fix Poles = 8 seconds
Fix Poles & Preserve Volume = 1 min 20 seconds
All enabled = 7 minutes 58 seconds
All except Fix Poles enabled = 5 seconds

Proposal

To provide a better experience for remeshing we should update the defaults.
Long term it would be better to improve the performance of the Fix Poles option but that is a bigger task.
So the new default options would be:

Fix Poles = Disabled
Preserve Volume = Enabled
Preserve Painted Mask = Enabled
Preserve Face Sets = Enabled
Preserve Color Attributes = Enabled

I just realized, I wasn't paying enough attention to this issue; users are complaining. I can probably fix the performance penalties in the remesher projection code which is extremely inefficient at the moment.
