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.

There are two max window size settings on macOS, `contentMaxSize` and
`maxFullScreenContentSize`. Set the latter to avoid a window being
resized larger than its maximum in full screen mode.

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.

When the window is created position it *before* processing the actions
to perform (which may include system.ActionCenter). Note that the
actions are performed in the callback windowProc().

An IME session must be discarded when its text content no longer matches
the underlying text component content. However, the check for matching
was too pessimistic; the IME session would be discarded if the new
snippet from the text component was not equal to the snippet reported to
the IME. This change implements a refined check that only discards a
session if the content of the overlap between the new and old snippets
don't match.
Fixes an IME issue reported by Zhang Zj.

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.

Setting the callback handler to nil in DestroyEvent should have no effect,
but may help debugging #603.
Also don't call the default window handler for WM_DESTROY since we're
already handling it.

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.

When a GPU error occurs forcing the reporting of a DestroyEvent is not
appropriate, because the backend that controls the underlying window
is not aware of the error and will continue to report events.
Replace the crude DestroyEvent by stashing the error and asking the
window nicely to close. The, report the stashed error in the
otherwise regular DestroyEvent.
Hopefully, this second attempt fixes#603.

As suggested by ~egonelbre, Decorations should not be the source of truth
for the windows state, because external gestures may also change state.
This breaking change removes Decorations.Perform and exposes Maximized

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.

This commit ensures that it is safe to invoke Invalidate() from another goroutine
while a Gio window may be in the process of closing. It can be difficult to prevent
this from happening, as window handles can easily be managed by a type that doesn't
know the exact moment of window close (it might be waiting on the window event loop
to return, but that hasn't happened yet). Without this change, the nil window
driver results in a panic in this situation.

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.

This commit ensures that attempting to perform a system window action prior
