This is built on D7532 to improve the animator's workflow when their mindset is to use the NLA as an animation layer system. This diff allows the tweak strip to be evaluated outside its strip bounds if flagged for action length syncing.addresses {T63675}
For this patch, It also allows keyschanges include {D7602} due to be inserted outside the strip's bounds.
the dependency but the only file of interest is //anim_sys.c//
**Problem**
The animator can not view the NLA result outside of the strip bounds. This is expected behaviour. However, if they have flagged the strip to sync with the action bounds then their expectation is for the strip to evaluate based on the action bounds, not the only-updated-on-tweak-exit strip bounds. Further, it's not possible to insert keys outside of the strip bounds. This results in a workflow where the animator must determine the strip bounds before making adjustments to the action. This isn't trivial to determine so it's a trial and error process.
**Solution**
The NLA system now evaluates the strip based on the action bounds if it's flagged for syncing. Now the animator can freely insert and modify keys outside of the strip bounds. They will never have to touch the strip bounds directly. Changing the evaluation bounds is a simple as moving keys around.
