bugfix(anim): Fix elapsed time of object animations

[xezon]

• Follow up for bugfix(fps): Fix and improve logic time step and render update decoupling 2 #1579
• Fixes Building scaffoldings don't animate until viewed #1641
• Merge after bugfix(fps): Fix crashes and ww3d updates in tools #1688
• Merge after bugfix(anim): Fix single animation updates #1702

This change is a follow up for #1579 and fixes the elapsed time of object animations. It also adds the elapsed time for seg line again.

The deal with these updates is that they are not guaranteed to update always, but are only updated when inside world view. That is why we need to keep track of the absolute time of the last update instead of accumulating the frame time every render update.

TODO

• Replicate in Generals

[xezon]

Generals will fail to compile until replicated.

Is it planned or expected that animations like the scaffold crane are properly scaled when fast-forwarding replays?

[xezon]

For sure. I have not yet made a pass on Fast Forwarding Time Scale. The feature needs to be reimplemented. The current implementation still uses the EA hacks.

[xezon]

Updated.

[xezon]

Rebased.
