The Windows Pointer API
(https://learn.microsoft.com/en-us/windows/win32/api/_inputmsg/) was used
to allow the detection of events when interacting with touch screens. This
also opens the gates for supporting other types of input devices (e.g. pens
and touchpads). Mouse events are now part of the pointer events (primary
events trigger WM_POINTER<DOWN|UP>, whereas secondary ones vanilla
WM_POINTERUPDATE, and cancellations WM_POINTERCAPTURECHANGED).
A fourth and fifth button (usually found in modern mice) has also been added
for completeness, though their integration in other OS-es shall be the
objective of future patches.

According to @kkeybbs, pressing the maximize button on Windows only
resizes the window up to its maximum bounds. That means we can leave the
button available, and only hide it when the window has a fixed size.

When Gio is embedded (such as on Android and iOS), we pretend that the
Go library is the main program by running Go main on the main thread.
To avoid deadlock, `app.Main` returns immediately to relinquish control
of the main thread.

This behaviour is suprising (what if something else runs after `app.Main`?)
and more importantly is not compatible with app global events received
by the main goroutine.

Something had to give, and this change starts a new goroutine for calling
Go's main.

Now, it's possible to launch one Gio app using a custom URI scheme, such as `gio://some/data`.

This feature is supported on Android, iOS, macOS and Windows, issuing a new transfer.URLEvent,
containing the URL launched. If the program is already open, one transfer.URLEvent will be
sent to the current  app.

Limitations:
On Windows, if the program listen to schemes (compiled with `-schemes`), then just a single
instance of the app can be open. In other words, just a single `myprogram.exe` can
be active.

Security:
Deeplinking have the same level of security of clipboard. Any other software can send such
information and read the content, without any restriction. That should not be used to transfer
sensible data, and can't be fully trusted.

Setup/Compiling:
In order to set the custom scheme, you need to use the new `-schemes` flag in `gogio`, using
as `-schemes gio` will listen to `gio://`.

If you are not using gogio you need to defined some values, which varies for each OS:

macOS/iOS - You need to define the following Properly List:
```
<key>CFBundleURLTypes</key>
<array>
  <dict>
        <key>CFBundleURLSchemes</key>
        <array>
          <string>yourCustomScheme</string>
        </array>
  </dict>
</array>
```

Windows - You need to compiling using -X argument:
```
-ldflags="-X "gioui.org/app.schemesURI=yourCustomScheme" -H=windowsgui"
```

Android - You need to add IntentFilter in GioActivity:
```
<intent-filter>
        <action android:name="android.intent.action.VIEW"></action>
        <category android:name="android.intent.category.DEFAULT"></category>
        <category android:name="android.intent.category.BROWSABLE"></category>
        <data android:scheme="yourCustomScheme"></data>
</intent-filter>
```

That assumes that you still using GioActivity and GioAppDelegate, otherwise more
changes are required.

Events are routed to a new app.Events, which are not linked to a specific window.
