With this change, the Shape function returns a clip.PathSpec
instead of a clip.Outline op. It is then possible to create
a clip.Outline or clip.Stroke op to fill the text path or
draw its stroke.

In commit 929e4dc12, the rules to send pointer.{Enter,Leave}
events were relaxed. Unfortunately, to be able to make use
of them was not straight forward as it required the transfer
target op to use the same handle as the hover one.
This patch eases this by allowing any handle for the target
as well as not requiring the hover op to be defined on the same
clip op as the target (then requiring a PassOp though), making
it much easier to use.
Also added a test for pointer.Enter events not being generated
if the target type does not match the source one.

When extracting headless.Window's content via screenshots,
it can be useful to keep reusing the same image for output,
as well as specify which area of the Window is to be
extracted.
The updated Screenshot method does this by using the supplied
image.
API change: users must pass an existing image to Window.Screenshot.

Ever since commit 8ff654628, the headless implementation has used two
GPU backend (not renderer) instances, one for the renderer and one for
creating the offscreen texture to render into. This arrangment leaks
resources because the backends only clear temporary storage at
BeginFrame, which is not called when reading pixel data from renders.
This change adds an internal constructor, gpu.NewWithDevice, to allow
headless.Window to share its device with the renderer, fixing the leak.
It also makes the code simpler (took me a while to debug this issue); in
fact I'm surprised it even works.
This is not a great fix: it adds an exported yet internal constructor,
and the ownership transfer of the device is surprising enough to warrant
two comments.

This change is to augment the X11 clipboard write behaviour.
When writing to the clipboard both the primary and clipboard
selections are published so that non-GIO applications that read
the primary selection (i.e. such as terminal emulators using
middle-mouse clicks) can read the data from a GIO app.

This patch adds internal Drag and Drop support to app.Windows.
The new package io/transfer adds the ability to

The API is generic and could handle future use
cases, such as external Drag and Drop.

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.

Icons have no inherent semantic meaning such as a label, so this change

This is an API change, because it seems best to force every client to
