apply abstract method

void apply(
  1. double progress,
  2. RouteNode incoming,
  3. RouteNode? outgoing
)

Poses both sides at progress by writing onto the routes, whose size is the region being routed. outgoing is null on a push, where nothing is leaving and the covered route is its Backdrop's to pose. Runs once when the navigation starts and once per tick after the clock moves, so rendering always sees the pose.

Implementation

void apply(double progress, RouteNode incoming, RouteNode? outgoing);
