Summary0003028: Backport Warp ACS function
DescriptionThis is somewhat a duplicate of 0002617, but this is more specific: backport the Warp ACS function to Zan 3.0. This is needed because:

1. ZDoom commit a0f19fc78879 removed interpolation from SetActorPosition, which made things like custom player cameras jittery
2. It's a pretty useful function that can make stuff like the aforementioned cameras easier.
Steps To ReproduceRun the attached WAD file (MAP01) in 2.1.2, and notice how the ACS third-person camera is smooth. Run it in 3.0, and notice how it lacks interpolation and is all jittery.

I'll also attach an example of how that camera would be implemented using Warp.
Additional InformationWarp is from 2.8.1, so backporting might be difficult?

Backporting the ACS Warp version from ZDoom 2.8.1 was not really feasible, but it was possible without risk to backport ZDoom's initial ACS Warp version. This should be sufficient as replacement for the old interpolating behavior of SetActorPosition.

Yeah, the GLOOME one you suggested seems sufficient for now.

EDIT: Woah, I didn't know you backported it already. Will test now

Yep, my attached Warp example works straight out the box in 3.0-170416-0710 and everything's nice and smooth and interpolated. I guess this and ticket 2617 can be considered resolved.
