[Feature] Local animation speed scaling

[MajorCooke]

I'm wondering if if there can be a variable that scales the animation speed for anything that's using systems such as VisualThinker's or a particles SPF_LOCAL_ANIM? Because while it's nice being able to define animations with ANIMDEFS, it'd be a bit of a pain if I had to make a new one each time whenever I want to change just one pic's tic duration.

So, would this be possible?
