CSS class name to apply for this keyframe.
This class name may pre-exist in an application stylesheet and be specified by the API consumer.
If not, it may be populated by the animation system to point to an emitted CSS class, depending on the AnimationProvider used.
Optional clip
clip:any
Optional color
color:any
Optional crop
crop:any
Optional duration
duration:number
The duration of this keyframe.
If this keyframe is a simply a reference to an existing CSS class, and no duration is provided, one
will need to be calculated. The act of calculating the duration will cause a layout calculation and should
thus be considered expensive.
It's always better to explicitly provide a duration if possible.
Optional fontSize
fontSize:any
Optional fontWeight
fontWeight:any
Optional height
height:any
Optional isDynamic
isDynamic:boolean
Whether or not this frame is dynamic. Frames that are dynamic do not need to be cached.
Frames calculated on the fly and only used once should be considered dynamic frames.
