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.

The fix for #616 went to far by attempting to support macOS key bindings
through doCommandBySelector. Issue #625 is a consequence, but more
fundamentally, key bindings does not work with support for key.Release
events.
Remove key binding translation and fix#626, and add a check whether an
IME swallowed a key event, keeping #616 fixed.
While here, replace the KEY_ constants with ASCII codes.

Widgets such as Editor use certain key events such as the backspace key
to implement text editing. On macOS, such key events are sometimes used
by an input method, and in those cases the key effect would be applied
twice: first by the IME and then the Editor.
Report such key events through the doCommandBySelector callback, which
receives key events not handled by the IME.

Before this change, the window state was explicitly updated whenever
Window.Option was called. However, the system may also change window
state as a result of user gestures, but those changes did not result in
ConfigEvents reflecting them.
Remove the explicit state updates and track them when the system tells
us it has changed.
This is a step towards fixing #600 which require accurate window state
tracking.

Instead of sending ViewEvents once at construction and once at destruction,
it's better to send them when the underlying NSView changes attachment.
The main advantage is that we're about to move the destruction and
emitting of DestroyEvent to the NSView's dealloc method. However, the
dealloc will not be called if user code has a strong reference to it
through a non-empty ViewEvent. By sending an empty ViewEvent when the
view is detached, well-behaving users will remove the strong reference.

Commit c0c25b777 replaced the synchronizing of the display link callback
from a sync.Map to a cgo.Handle. However, the change didn't take into
account the lifecycle issues: a callback may happen just as the cgo.Handle
is freed, leading to a misuse crash.
This change restores the sync.Map synchronization, which avoids the
lifecycle issue.

before the window is gone. This change moves cleanup to the

We used to track the pressed pointer buttons through the global function
[NSEvent pressedMouseButtons]. However, it's possible that at the time a pointer
press event is delivered, the pointer button is up again. To ensure a consistent
view of the pointer press state, track it through the buttonNumber property on
delivered events.

Switching to using a CAMetalLayer as the layer backing our NSView
implementation broke programs such as the opengl example. Somehow, using
ANGLE on top of a CAMetalLayer (but not a CAEAGLLayer) stops resizes
from triggering redraws.

and no longer rely on the implicit redraws.
