vkDeviceWaitIdle and vkQueueWaitIdle are expensive; a vkFence is cheaper
and the usual way to ensure a previous frame has completed before starting
another.

After 34f10d9cbb, the display link callback
will never block. However, if the main thread is blocked for another reason,
say a bug in the user program, callback requests will pile up as blocked
goroutines.
This change ensures that a redraw request is queued only if no other request
is pending.

Previously, the window size is equal to the screen size. That doesn't
consider the size of the taskbar, causing the height be bigger than the
real height. Now, the maximized have the same behavior of windowed,
since both of them must include decorations and taskbar.

This reverts commit 11f39582b8 that
introduced pacing of display link callbacks. Blocking the display link
callback introduced deadlocks with code that updates the display link
display.
Not pacing the display link may introduce extra view invalidations,
but invalidates are consolidated by the system and won't result in
extra redraws.

Mapping it to key.NameReturn confuses widgets such as Editor that

Apparently, a Wayland server such as Sway and River may not issue
a frame pacing callback created before a top level configure event.
This change ensures the frame pacing callback is always refreshed
when animating, regardless of the reason for the frame.

When a text range in the IME snippet is replaced, the replacement
is discarded if the range don't overlap with the snippet range. However,
the replacement is more relevant than whatever snippet is current.
This change discards the snippet in case of no overlap.
As a bonus, IMEs that leaves the snippet range at [0:0] will have the
snippet track the composing region now.
The FuzzIME test is adjusted to always generate replacements that overlap
Editor content; otherwise the IME snippet and editor state can't be expected
to match.

This commit changes the definition of app.ViewEvent on Unix systems
to be an interface implemented by two different concrete types:
X11ViewEvent and WaylandViewEvent. Each provides the necessary fields
for custom rendering on its display protocol.
This is a breaking change for all users of app.ViewEvent on
Linux/BSD, as it now is an interface instead of a concrete type.

The fix for #340, b2a99fddca, deferred
all driver functions until after event processing. Deferring functions
breaks Window.Run which expects to complete during event processing.
This change is an alternative, more targeted fix, namely deferring just
Window.Close until after event processing.
A follow-up will revert the previous fix.
