For mixing native UI with Gio UI, the UIViewController is sometimes
needed, not just the UIView. This change replace the View field of
ViewEvent with ViewController.

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.

Previous changes added semantic API and semantic information to Gio
widgets. This change maps the information to Android accessibility

Some semantic information is automatically extracted, but some must be

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.

Switch needs a semantic description, but doesn't have a text label
attached. This change adds a description argument to the constructor.

Icons have no inherent semantic meaning such as a label, so this change
adds another argument to the IconButton constructor for the client to
provide a description.
This is an API change, because it seems best to force every client to
provide semantic descriptions for icon buttons.

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.

This comment and associated code were designed to guard against
the scrollbar failing to anchor to the proper edge of the content
when the layout.Direction was used with a zero minimum constraint.
However, they were in the wrong place to actually achieve the
desired behavior. This change simply moves the constraints
change to before the invocation of layout.Direction's Layout
method. This fixes the scrollbar appearing on the wrong edge of
content when the content is laid out with a zero minimum constraint.
