Feature: input processor behavior invocation (#2714)

refactor(pointing): Allow stopping event propagation

    Allow input processors to return a special value if a given input event
    should not be further processed/propagated.

feat(pointing): Add behavior input processor

    Add the ability to intercept certain input events and trigger behaviors
    when they occur.
