Bug description

the UDFPS custom animation runs at the screen framerate, so if 'smooth display' is enabled in display settings it will play at twice the intended speed.

Steps to reproduce

1. enable setting: crdroid > lockscreen > udfps custom animation
2. enable setting: display > smooth display
   2.a. make sure battery saver is off

Solution

play the animation using its framerate instead of the screen's refresh rate, and (if possible) use higher framerate versions of the animation if smooth display is on

this is how it works
