Post a dedicated message upon Window.SetCursor calls.
Make sure that the cursor is only changed if the cursor is in the window.

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
context-menu is to "Save image": which gives a black image.
I think it's better to remove it. The right-click still work and still
provide `pointer.Event`.

First, don't filter on HWND in GetMessage and PeekMessage, lest
thread-specific messages may get lost. See

Second, replace the dead status with the detection of WM_QUIT; it's
what it's there for.

Wayland doesn't guarantee the presence of server-side window decorations
(border, close/maximize/minimize buttons), and Gio doesn't have client-side
decorations either (issue #29). The issue is more than a year old, so it's time
to default to X11 to have a good out-of-the-box experience on unix systems.

An event reporting the most recent Android View attached to the Window is both
simpler to implement and automatically tracks the Activity lifecycle.
The downside is that buggy programs may hold on to a stale references.
Fortunately, JNI references are handles not pointers so the always-on Android
JNI checks will very likely catch stale references on use.
