In .X ascii files, the speed of the animation is stored as a template that follows this format:
// This can be found in many ascii .X files, and can be added to ascii
// .X files that do not contain it.
AnimTicksPerSecond
{
<ticks per second>;
}
We add an <animtickspersecond> node because the content pipeline processors give no information on keyframe indices to the processor; they just store keyframes as time/transform pairs. Note that adding this node is optional if we want to split up the animation by time rather than by keyframe index
