<!-- This benchmark aims to accurately measure the time it takes for Skottie to load the JSON and
|
|
turn it into an animation, as well as the times for the first hundred frames (and, as a subcomponent
|
|
of that, the seek times of the first hundred frames). This is set to mimic how a real-world user
|
|
would display the animation (e.g. using clock time to determine where to seek, not frame numbers).
