Test the version 21.04 Pre-release

@brian, was anything with improving the Blend mode you mentioned here:

I have to admit that the blend mode is very crude. I believe that we occasionally see frames blended when the speed is 1.0000x due to rounding errors. I think that instead of adding an option, I just need to make the blend mode match people’s expectations.

  • For 1.0x, there should be no blending as you suggest.
  • For <1.0x, it should blend between two frames proportional to the distance between the two frames of the ideal time. For example, if the mapped time calculates to frame 1.25, then it should blend frame 1 at 75% and frame 2 at 25%.

I will keep this in mind and look for a good opportunity to improve the blending logic.

done for this version?
