The NSViewGlobalFrameDidChangeNotification notification is documented to
be fired every time [NSOpenGLContext update] needs to be called.
However, the notification fails to fire on my setup when a window is
moved to a display with a different pixel scale, which leads to
incorrectly sized output.
This change gets rid of the notification and updates the context before
every frame.

Previously, the on-screen keyboard always displays the text keyboard,
(QWERTY or equivalent).
For optimal user experience, it's possible to specify the keyboard type
using `InputHint`. The on-screen keyboard will provide shortcuts or
restrict what the user can input.
Due to some limitations (gio#116), only numeric and text keyboards are
supported on Android.

This changes moves the macOS specific setup for desktop OpenGL to the
portable opengl package. The opengl package already takes care of the
desktop OpenGL setup for sRGB framebuffers, and by moving the code we
avoid calling the wrong OpenGL functions in case both OpenGL.framework
and ANGLE libGLESv2.dylib is linked into the program.
Remove the interface casting expressions for gl.Functions; it wasn't
worth the trouble to keep updated.

Native window callbacks now run in the same context as the event loop.
However, a call to Close immediately calls onClose which in turn wants
to send events. Break the deadlock by deferring the Close call.

GioActivity is final to avoid the brittle base class problem. However,
to permit replacement of GioActivity the GioView delegate methods must
be public.
While here fix a function signature, rename lowMemory to onLowMemory and make it
static. Also move view specific setup to GioView, simplifying the host
activity further.

app.Window implements a method for safely running functions against the
underlying native window through the driverFuncs channel. However, the
functions still run in a different goroutine than the one driving the
native event loop, which forces the implementations in package wm to do
complicated synchronization.
A previous change added a mechanism to run functions in the native event
loop thread. The macOS port needed this functionality, but with some
care it can be generalized. That's what this change does through the
new Run method.
The advantage is that the thread switch dance is now confined to
app.Window, with the help of a generic wm.Driver.Wakeup method. All
other Driver methods can then assume they run on their event loop
threads.
Run is exported because it is also needed for programs that use
Windows configured with CustomRenderer to control their own rendering.

CustomRenderer disables the construction and binding of a GPU
context to the Window. Combined with ViewEvent and gpu.New, a Gio
client can mix Gio UI and custom rendering.

macOS is the only platform where desktop OpenGL is used. To support
foreign ANGLE contexts add a setting to override Gio's selection of
OpenGL implementation.
The bulk of this change is making all function pointers per-context
instead of global, and loading the OpenGL library dynamically. As a side
effect we're closer to Gio tolerating a platform without any OpenGL
implementation. For example, Apple has deprecated OpenGL and OpenGL ES
on its platforms and may remove them in the future.
Note that as a side-effect of this change, Gio needs Go 1.16 or newer to
run on iOS.

NewDevice creates a Device given an API, which is the necessary GPU

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

It also allows programs that embed Gio (such as gioui.org/example/glfw)
to freely choose a backend, not just OpenGL.
