It's now possible to directly user pointer.Cursor to add to the ops.
pointer.CursorText.Add(gtx.Ops)
This is an API change. Use pointer.Cursor directly instead of CursorNameOp.

Add most of the common cursors defined by different systems.
Normalize cursor names to match CSS.
This is API change: some cursor names have changed, and the
underlying type is no longer a string.

Mapping it to key.NameReturn confuses widgets such as Editor that
treats clicks separate from return key presses.

This change implements reporting of the caret position from Editor, as well
as Windows, macOS, Android support. As a result, the IME composition window
on Windows and macOS is now positioned correctly.

This patch adds internal Drag and Drop support to app.Windows.
The new package io/transfer adds the ability to
define draggable and droppable targets, which
are leveraged by the new widget.Draggable type.
The API is generic and could handle future use
cases, such as external Drag and Drop.
Updates gio#153

Software such as screen readers require semantic descriptions of user
interfaces to effectively present and interact with them. Package
semantic, combined with the existing package clip provide the operations
for Gio programs to describe themselves.
This change implements the semantic package and the routing changes for
accessing semantic trees; follow-ups add semantic information to widgets
and implement mapping semantic tree to platform representations.

Pointer hit areas and paint clip areas are separate concepts, but
similar enough to warrant merging. This change replaces pointer hit
areas with clip areas, so Gio is left with just one area concept (in
package op/clip).
The reason for separating the concepts in the original Gio release was
because of my being unsure general path/stroke hit areas would ever be
implemented, let alone efficient.
This change represents a change of mind, in the sense that it's better
to have an incomplete API than two separate area concepts.
Leave the deprecated pointer.Rect, pointer.Ellipse for temporary
backwards compatibility.
This is an API change. Most existing programs should continue to build
with this change, but may have to adjust to having all clip.Ops participate
in InputOp hit areas.

Like a previous change for pointer ops, process key ops during the
router decode of ops. This is a performance optimization and preparation
for processing future accessibility ops without without another decode
loop.

The router package decodes the entire ops list thrice: once for pointer
ops, once for key ops, once for other ops. This change removes one
decode round by merging other ops and pointer ops decoding.

Since the Process* methods on clipboardQueue are called while decoding
the ops, no need to recheck for the op type.

Previously, the on-screen keyboard always displays the text keyboard,
(QWERTY or equivalent).
For optimal user experience, it's possible to specify the keyboard type
using `InputHint`. The on-screen keyboard will provide shortcuts or
restrict what the user can input.
Due to some limitations (gio#116), only numeric and text keyboards are
supported on Android.

key.InputOp and pointer.InputOp handlers are reset on first registration
through a key.FocusEvent{false} or pointer.Cancel, respectively.
However, the mere act of registering a handle shouldn't result in a
redraw. This is particularly true for misconfigured handlers where a new
tag is supplied every frame, resulting in continously redrawing.

Previously, the only way to manipulate the clipboard (read or write) is
using the `app.Window`.
The new `clipboard.ReadOp` and `clipboard.WriteOp`makes possible to
read/write from the widget.

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

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 .

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.
