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.

Custom rendering applications need to be prepared to handle empty view events,
as an empty view event is sent during window shutdown. However, the current
implementation requires applications to write a platform-specific helper
function for each supported platform in order to check whether a received
view event is empty. This commit provides a safe, convenient, cross-platform
method that applications can use to detect this special view event and respond
to it.

A uniform type allows convenient nil checks and for future window
backends on platforms other than Linux (which already had ViewEvent
as an interface).

This change gets rid of the event.Queue interface by replacing it with
input.Source values. Source provides the interface to Router necessary
to implement interface widgets.

We're about to replace the interface Queue with a concrete input.Source.
This change renames the field accordingly.

In the early days of Gio, FrameEvent was part of package app. It was
moved to package system to enable layout.NewContext be a convenient
short-hand for constructing a layout.
However, it seems the better design to leave FrameEvent (and Insets) in
package app, and move layout.NewContext there as well. More importantly,
the move allows us to replace the event.Queue interface with a concrete
type.

Allow app ID to be set by linger flag -X gioui.org/app.ID=%s so that wayland
can group windows, search for ${gioui.org/app.ID}.desktop file and display
application name. e.g. /usr/share/applications/${gioui.org/app.ID}.desktop
~/.local/share/applications/${appID}.desktop.
ID is set by the gogio tool or manually with the -X linker flag.

The app and app/internal/wm packages are tightly coupled, requiring
quite a bit of forwarding types, values and constants from the internal
package to export it. Further, no other package imports package wm.
This change merges the two packages.
While here, drop the pre-Go 1.14 SIGPIPE workaround.

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.

Package wm (for "window manager") is a better fit for the package, and
distinguishes it from the low-level package windows for the Windows API.

This CL implements the app.Main function as a blocking-forever function
for JS, Wayland, Windows and X11.
This works better for applications that can now programmatically close
windows.
RegisterFragment creates an instance of a Java class and registers
it as a Fragment in the window's Context.

Package app is the only package that depends on native libraries and
Cgo. Minimize its API, thereby minimizing Gio clients' dependency on
it. In the future, a headless, testing or remote "Window" should be
very easy to replace app.Window.

While "DrawEvent" was too specific (op.Ops contains non-draw events),
"Update" is too vague: it's a common word, and could be misunderstood
to mean update parts of a window, not replace it.
"FrameEvent" is more specific, and is the usual way to refer to immediate
mode drawing.
While we're here, unexport Window.Update and add a Frame function to
FrameEvent, to emphasize that updating the window frame is only
appropriate during the handling of a FrameEvent.
