And add ProfileOp and ProfileEvent for registering and receiving
profile data.
Remove the Profiling field and Timings method from app.Window.

Redrawing should only be scheduled when some UI state has changed.
Window has no way to know whether a CommandEvent was ignored by
the client, so push the onus to the client to schedule a redraw.

Single stepping events only makes sense for widgets with complex
state, e.g. the text.Editor. For the input.Events source, returning
all events in a single Events call is sufficient and more natural
for clients.

Before this change, the weight applied to the space left, not the
total space available after rigid children.
While here, ensure that weight sums > 1 are capped to the available
space.

The type and argument to Flex.Flexible does not carry its weight;
It is just as easy to expand the constraint directly.
While we're here, rename the flex argument to weight which is clearer.
With this change, a List l can be iterated with
for l.Init(...); l.More(); l.Next() {
l.Elem(..., l.Constraints(), l.Index())
}
instead of
l.Init(...)
for {
i, cs, ok := l.Next()
if !ok {
break
}
l.End(..., cs, i))
}

Insets is like image.Rectangle, but with properly named fields
and ui.Value instead of raw ints to make use with the layout
package easier.

The verbose flag only triggered printing of commands, which is
traditionally named -x by other Go tools.
The -work flag will print and preserve the temporary directory.

Let the caller decide whether the constraints should be stretched.
Also unexport Constraint (not Constraints) methods, they weren't
pulling their weight.
Finally, don't force cross axis constraint minimum to 0 in List.

Now that the pass through mode is moved into its own PassOp op,
it doesn't make sense to collect all area types into one exported
type.
Add RectAreaOp and EllipseAreaOp for clients; the internal
representation is still a single op. It can be changed later without
breaking clients.

Get rid of the confused LayerOp and the transparent property from
AreaOp. Add an explicit PassOp to specify whether pointer events
pass-through the current area.
Let AreaOp swallow events even when no handlers are active for the
area. That behaviour is less surprising and allow clients to disable
a widget by keeping its areas but leave out its handlers.
Simplify the pointer.HitResult enum to just a bool: hit or no hit.
Finally, simplify the pointer queue by tracking parent areas and
node with indices.
To keep the interface slim, remove the helper methods and shorten
the essential method, Pixels, to Px.
Add and use unexported Config implementation in the app package.
