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.

Even when a command defers event delivery to the next frame, the already
observed events must still be delivered in the current frame. This
matters for pointer events that hit more than one event handler.

This commit ensures that attempting to perform a system window action prior
to the first call to Event() does not panic. It adopts a similar strategy to
handling Option() prior to the first call to Event(): make a slice of the arguments
and apply them during window initialization.

Previously it uses event.Op{}, but such struct don't
exists anymore. Instead, it have a function with the

Up until now, the iOS part has relied on a tool such as gogio to
synthesize a main function. This change adds support for running direcetly
in exe mode, while retaining support for embedded Gio in C programs.

We're moving towards making Window.Event, and in the future, Window.Events
create the window and drive the event loop to completion. In that model,
the other Window methods shouldn't create the window.

With this change the GPU renderer now properly handles the cases when the stroke width equals the stroke length where the normal vector is the same size as the original vector.

According to #565 X11 GPU drivers don't deal well with recreation of
EGL surfaces.
Thanks to Walter Schneider for debugging this issue and coming up with
the original patch.

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.

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.
