On large bitfields, emscripten creates types such as
i472, which 'legalization passes don't know how to
convert into legal code'
Adding a dummy field every 64 bits forces alignment
which in turn forces emscripten to create i64 types
instead.

We’ve already set up emscripten_set_main_loop_arg to
call the main loop callback using requestAnimationFrame.

Pause main loop updates when no updates have been requested.
Restart when requestUpdate() is called again.

Applications can now be completely idle when there
are no updates, or animate continuously if requestUpdate()
is called at the end of the paint event.

Use native timers to wake up when there are pending
events and when its time to activate Qt timers.

Make processEvents() process one round of events by
removing the loop that processes until hasPendingEvents()
returns false. Instead, check hasPendingEvents() before
returning control to the browser and schedule a zero-
timer if there are pending events. This way all events
will be processed without triggering the “unresponsive
page” timeout in the browser.

Use QTimerList to map all Qt timers down to a single
native timer by scheduling a wakeup when the fist
Qt timer should fire.

Making this work requires adjusting the native timer
whenever events are posted or Qt timers are modified.
In practice this is done by calling maintainTimers()
as the very last thing in callbacks we install with emscripten.

The change to fix 16-bit integer overflow used two floor operations
when only one is necessary. With floor being rather expensive on x86
without SSE4.1 this caused a performance regression in ARGB32
smooth perspective transforms.

This eliminates one of the floor operations which is unnecessary as the
number is always positive in this case and thus truncation will yield
the same result faster.

it intended to change, and those must be done in an async-signal-safe

middle of some code.
