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

API change. Update your code with gofmt rule and goimports:
gofmt -r "system.ClipboardEvent -> clipboard.Event"

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.

Recently support was added for multiple top-level windows. Add support
for closing those windows.
macOS only; all others stubbed out.

An interface for scaling dp and sp is overkill, at least for all
current uses. Make it a concrete struct type, and rename it to the
shorter and more precise Metric.

Do is a function for accessing the underlying Android View in a safe
context, the main thread. Do is
- more general than RegisterFragment and may be expanded to other platforms
- simpler to implement (from the Gio side)
and as a bonus, the Do implementation avoids a race condition where
a call to RegisterFragment during an Activity re-create would be ignored.

The Activity context may not be available, so it's safer and simpler
to use the always available app context.

Then, make layout.Context.Now a field, copied from FrameEvent.Now.
API change:
gofmt -r 'gtx.Now() -> gtx.Now'

Android apps may want to run Go code independent of the Gio Android Activity.
Expose a Gio.init Java method public for early loading and initialization of
the Go library.

There can only be one JNI_OnLoad callback per JNI library, and the
Gio program may need it for its own purposes.
Gio only used JNI_OnLoad for explicitly registering native methods. Switch
to implicit name based registration and get rid of JNI_OnLoad.

We're about to remove the global JNI_OnLoad constructor, and the
JavaVM singleton is just as easily fetched from a Java JNI callback.

While we're here,
- replace the registerFragment trampoline with a general variadic
CallVoidMethod trampoline.
- Use UTF-16 for passing strings to Java. Java's modified UTF-8 encoding differ
from Go's in corner cases.

This is the kind of event one gets when using 'adb shell input tap x y',
which I am trying to use for the end-to-end tests.
Right now, we only have two pointer source types: mouse and touch.
On Android, emulated touch events tend to simulate the touchscreen, not
a mouse, so let's go with that as a fallback.
Perhaps in the future we will have another special pointer source for
this kind of event, such as "unknown" or "virtual".

RegisterFragment creates an instance of a Java class and registers
it as a Fragment in the window's Context.

Function keys don't have a natural rune representation so switch
Event.Name to be a string to fit "F1"-"F12".
