Document timingFunction easings.

[UrkiMimi]

Is your feature request related to a problem? Please describe.
Currently, you can edit the animations specified in the msstyles file but you can't edit the easings for said animation. As a result, animation easings are restricted to the ones that came with the file.

Describe the solution you'd like
Having some sort of option would be helpful. I'm not sure how easings are specified inside the themes (if its curve or type based)

Describe alternatives you've considered
None

Additional context
Also none

Sorry for the late response. I never tried, but I think you are looking for the timingfunction class ("Class View" window). There you can set a cubic bezier function for various animations and with it change the easings. No idea why Microsoft hasn't made those curves properties of the animations itself...

timingFunction is pretty much what I'm looking for. However, I feel like these values should have some documentation instead of needing to find out what they do.

I'll change the name to reflect this since they are supported, just not documented well.
