To make the semantic relation between the clickable area and its
content clear, it will be important for the clickable clip operation
to cover all of the clickable content.
API change: users of widget.Clickable must now pass the clickable
content to Layout.

The click area was mistakenly offset by half the track width, but it
really should be offset by half the thumb diameter.

Commit 9835cd59 added support for the Window.Maximize and

This patch also adds support for macOS and X11.

Before this patch, use of `app.Fullscreen` would result in "Failed to

When the rectangle used in an Ellipse has no width
or height, the path would panic with "path not closed".
Use an empty rectangle path in that case instead.

On headless setups such as sr.ht CI machines, lavapipe is the only

driver for headless contexts, so that CI won't fall back to OpenGL.

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.

op.Save, op.SaveStack were compatibility stop-gaps.
API change. Most op.Save/Loads can safely be removed altogether, or
replaced with
trans := op.Offset(f32.Pt(0, 0).Push(gtx.Ops)
...
trans.Pop()
cl := clip.Rect(image.Rect(-1e6, -1e6, 1e6, 1e6)).Push(gtx.Ops)

Like a previous change for pointer ops, process key ops during the
