As reported By Larry Clapp, Wayland would send a ConfigEvent with
every FrameEvent when fallback client side decorations are enabled.
This is because Window would call the driver Option and Perform
methods even when they're empty.
The change applies to every platform, but was only observable on
Wayland.

Before this change, a FrameEvent may be delivered after DestroyEvent,
leading to a panic. Destroy the X11 window immediately thus ensuring no
events can be delivered after destroy.

Don't call eventLoop.FlushEvents which in turn applies Options and
executes Run functions before the window is fully initialized.

A single image.Rectangle for the scroll bounds introduced a subtle issue
with zero area rectangles (see #572). To avoid that and similar issues,
split the bounds into two separate one-dimensional ranges.

FBOs and window framebuffers generally have different pixel formats, and

StageEvent served only redundant purposes:
- To detect whether the window has focus. That is covered by
key.FocusEvent.
- To detect whether the window is currently visible. That is covered by
the absence or presence of FrameEvents.
- To detect when the window native handle is valid. That is
covered by ViewEvent.

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

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.

Their absense didn't make a practical difference so far, but we're about
to refactor the macOS event processing loop where the pools do matter.
Signed-off-by: Elias Naur <mail@eliasnaur.com>
This is mostly a refactor, but there are two user-visible effects:
- Window.NextEvent may be called even after DestroyEvent is returned.
- Window.Invalidate always wakes up a blocking NextEvent, even when a
FrameEvent cannot be generated.
As a nice side-effect, X11, Wayland and Wasm no longer require separate
goroutines for their window loops.

Now (*widget.Selectable).Update() returns whether the selection changed during
event processing, rather than requiring a separate call to (*widget.Selectable).Events().
The Events() method has been removed as redundant.

This commit eliminates (*widget.Editor).Events() in favor of making
(*widget.Editor).Update() return events as they are generated in response to
input. This makes the behavior of the editor match the rest of the core widgets.
Callers who previously invoked Events() can now achieve the same thing by using
a loop like this:
for {
ev, ok := editor.Update(gtx)
if !ok {
break
}
// Handle ev
}
This is undeniably more verbose, but it enables more sophisticated event processing.

Widgets have themselves as tags, by convention, and so it's possible to

The empty key.Filter.Name now means matching every key name. This is a
replacement for the previous special case where the top-level key.InputOp
handler would get all unmatched events.
Add special case for system events such as focus switch shortcuts.

New handlers receive reset events the first time Source.Event is called.
However, in case the filter doesn't match a reset event it shouldn't be

It's semantically problematic that a zero Kind matches Cancel, and
outweighs the downside of having to explicitly mention Cancel in filters.
For example, GrabCmd was always deferred because the resulting Cancel
events always match the processed filters.
Remove Frame from a few tests now that GrabCmd can be executed
immediately.

Replace the key.Filter.Target field with a Focus field that matches only
of the specified tag has focus. This has the advantage of simpler event
delivery and for lower latency in delivering key events to new handlers.
For example, consider a UI where a button is activated by a key press,
which is turn displays a dialog with another button activated by the
same key. This change allows two button press(+releases) in the same frame
to arrive at the intended targets: one key press(+release) for each
button.

Until now, every event has had a particular target. We're about to simplify
key event delivery to match the first matching filter, so there is no
longer a global meaning to the tag argument to Source.Event.
Add fields to filters to specify their target tags.
