We're about the merge the Direct3D backend into package gpu. Extract the
raw Direct3D API to its own package, just like package glimpl.

NewDevice creates a Device given an API, which is the necessary GPU
resources for a backend.
Convert gpu.New to take an API instead of a backend.Device directly.
In turn, this frees us to later unexport the backend package along with
the backend implementations (for now just gioui.org/gpu/gl for OpenGL).
It also allows programs that embed Gio (such as gioui.org/example/glfw)
to freely choose a backend, not just OpenGL.

Completing the goal of allowing foreign Direct3D contexts for our
D3D backend, slim down the constructor to take only the device handle.

For example, ButtonLeft may be the right-most button for a left-handed user.
Rename the button names to match their intended use.
This is an API change. Use the following commands to update your
projects:
$ gofmt -r 'pointer.ButtonLeft -> pointer.ButtonPrimary' -w .
$ gofmt -r 'pointer.ButtonRight -> pointer.ButtonSecondary' -w .
$ gofmt -r 'pointer.ButtonMiddle -> pointer.ButtonTertiary' -w .

A previous commit removed the assumption that the output framebuffer
is constant across frames. Thus it is no longer necessary to track
and update a backend's current framebuffer when the window is resized.

The Wayland protocol implicitly dup(2)s the pipe write end descriptor passed to
wl_data_offer_receive. As long as we also have an open descriptor for the write
end, the pipe will not close and signal the completion of the clipboard read.
This change explicitly and immediately closes our write descriptor. Before this
change, reading the Wayland clipboard worked with some delay because the Go
garbage collector closed the write end of the transfer pipe after some time.

Post a dedicated message upon Window.SetCursor calls.

Android can re-create our Activity and GioView at any time, losing view
and activity state such as the current cursor. Further, setting state
while there is no GioView attached is lost.
Track the current and unapplied state, and apply it when a GioView is
available.

We're about to remove all references to window from runOnMain callbacks.
The JNI methods are constant and can be moved out of window.

Track whether requestAnimationCallback has been called when SetAnimating
changes the animated state of the window. Multiple callbacks result in wasteful
redraws.
Without this change, my browser becomes unresponsive when Window.Invalidate
is called every frame. Calling Invalidate every frame is a misuse (InvalidateOp
should be used for animation), but it's nice to have reasonable behaviour.
This change might also fix the issues described in
https://github.com/gioui/gio/pull/7.

Modern graphics APIs have immutable objects, with mutable data. For example,
a texture's dimensions are immutable, while the texture contents is not.
Change the GPU API abstraction to match.
Clearing a Texture is convenient to do with a plain []byte. Generalize
Texture.Upload to take a plain byte slice and introduce a helper function for
uploading *image.RGBA data.
Add TextureFormatRGBA8 a format for the linear RGB colorspace.
Add OpenGL ES 3.1 functions for compute programs.

Currently, on iOS, the keyboard can block the content since it doesn't
trigger the "resize". Now, the `insets` will provide the size of the
keyboard (on iOS) and scrollbars. It's compatible with the Android (and
desktop), but Chrome automatic resizes the windows, so the `Inset` will
be 0.

Previously, the keyboard is open by default, even without any focus.
Now, the keyboard will remain closed, until `.focus()` is called. That
change also prevents the keyboard from reopening immediately after blur.

As a consequence, most API is gone from gpu/gl, and embedding Gio in
foreign frameworks don't need to provide an OpenGL implementation.
The next change simplifies the GLFW embedding example accordingly.

To get the `popstate` we need to create a new entry into
the browser history. Then, Gio will handle the "back" and
"forward" of the page.
In some browsers (Chrome 87/Edge 87): The user must
click inside the window/page at least one time. It will not
work if the user leaves the page (clicking back button)
without interaction with Gio.

That change mitigates the issue gio#150 and gio#166. The
iOS can only `focus()` as a response to touchstart/click
events. We can't `focus()` at random, without user interaction.
The `w.requestFocus` will try to focus on the next `touchstart`,
which may need some "double click" in some cases. That mitigates
the issue, but doesn't fixes completely, but open the keyboard. (:
I didn't notice any side-effect of that change on Android and on
Windows.

The context-menu seems useless. The only action available, on the

I think it's better to remove it. The right-click still work and still
