- solutions_, failures_ as SolutionBaseConstPtrs in StagePrivate
- replace processSolutions() / processFailures() by direct const-access to storage containers
- generic sendForward(), sendBackward(), spawn(), connect() methods in StagePrivate
- reuse StagePrivate's sendForward(), sendBackward(), spawn() in containers
- store created InterfaceStates in StagePrivate::states_
- Interface: ordered<InterfaceState*> (only store pointers)
allows for common handling of states of valid and failure solutions
- remove additional state+solution storages
- containers: internal->external state mapping as InterfaceState* -> InterfaceState*
- code simplification
- allow slider interaction at any time
- keep last frame visible if animation finished
- animating_ is true iff animation is running
(previously it was also used to indicate the end of an animation cycle)
- renamed showMarkers() -> addMarkers()
- MarkerVisualizationProperty: renamed visible_markers_ -> hosted_markers_
Hosted markers are not neccessarily visible,
only if the corresponding namespace group is enabled.
- store "failure" solutions to facilitate debugging
- Introspection assigns solution IDs as soon as they are created in a stage
Thus, solution IDs represent their creation order.
In contrast, the order of publishing (in StageStatistics) should
represent the cost order.
- Storing failures is disabled if Introspection is not available.
The task id was not unique enough to distinguish different tasks.
When a task publisher is killed and restarted, it usually comes up with
the same task id. However, visualization doesn't notice this change and
get confused / crashes when receiving task statistics and solutions.
- only attempt to retrieve solution if remote was not yet destroyed
- setting get_solution_client is neccessary only once (pointer never changes)
- more reliable topic handling + status feedback
- locking: suppress interrupting current solution display when navigating solutions
- display end scene at the end of a solution display
- allow to display multiple solutions (its markers)
