Current dimension value (the playhead).
Dimension range minimum.
Dimension range maximum.
Step size for discrete dimensions; null = continuous.
OptionalgridThe dimension's own discrete grid step (its authored step), or
null/undefined for a continuous dimension. When max is off that grid,
the last grid point below it is the effective end of the range: the
dims manager snaps every write onto the grid, so clamping onto max
would land back on the current value and freeze playback there.
Current playback direction.
Boundary behavior: once | loop | bounce.
Target playback FPS (sizes the continuous increment).
Full-range traverse time for continuous dimensions, in ms.
Inputs for one playback advance step.
