This commit updates the implementation of the Enter/Leave pointer
events so that it no longer shares any state with the processing
of pointer presses and grabs. This simplifies the implementation,
though it does leave a certain amount of structural redundancy.

This commit introduces a naive system for sending events
when a pointer enters or leaves a pointer hit area.

For integrating with external window implementations (replacing
package app), access to the event router is required. Extract it
and put it into the new package router.
Router may belong in package io/event, but can't without introducing
import cycles.
