Fixes a problem where a touch Release would signal gesture.Click
that it had left just before click would complete.

There may be unrelated events in the queue, so it's not appropriate
to clear the queue just because an input Cancel event occurs.

Replace the pointer.Scroll special case with a new priority that
indicates the foremost handler, checked in gesture.Scroll.

This eliminates needless redraws for handlers that care about drag events and not move events, like gesture.Scroll.

- Drop pointer.Event.Hit in favour of Enter/Leave events.
- Track enter/leaves for each pointer.ID (updates #122). Add test.
- Resolve grabs once.
- Get rid of scratch slice.

Key had an unfortunate association with keyboard input.
This is an API change. The following rewrites were run to fixup
Gio code:
$ gofmt -r 'pointer.InputOp{Key:a} -> pointer.InputOp{Tag:a}' -w .
$ gofmt -r 'pointer.InputOp{Key:a, Grab:b} -> pointer.InputOp{Tag:a, Grab:b}' -w .
$ gofmt -r 'key.InputOp{Key:a} -> key.InputOp{Tag:a}' -w .
$ gofmt -r 'key.InputOp{Key:a, Focus:b} -> key.InputOp{Tag:a, Focus:b}' -w .
$ gofmt -r 'event.Key -> event.Tag' -w .

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.
