This is a more elegant way to sample from a float alpha texture.
Instead of sampling from the red channel in the fragment shader
we can set the alpha channel swizzle to redirect it to the
red channel. This lets us sample from the alpha channel in the
fragment shader and get the correct value.

Some permissions are associated with gids, so we need to
kill any running processes if their permission is revoked.
We will do this for any permission being revoked, since
the association between gids and permissions can change
over time.

The copied-to LinkProperties needs the same iface name as the copied from.
Since we were copying into an empty LP this was trivial, but I
changed the params to tighten up this contract - don't want to
accidentally change an LP's iface name when we shouldn't.

The trackball to dpad synthesis was using the MotionEvent's precision
field to determine a threshold for movement but the calculations
involved did not actually make sense for any value of precision
less than 2.0. This worked fine before since the InputReader
hardcodes the trackball's precision to 6.
Injected trackball events may have a different precision which can
result in the thresholds being set inappropriately. For example,
it was not possible to move focus by one unit at a time when
the precision was set to 1.0.
The old code was probably using precision as a way to set a
threshold based on the trackball moving by some minimum number
of physical ticks, in this case 2. But the code will work just
as well if we set an absolute threshold based on distance
traveled given that the input system is already expected to
normalize the trackball movements before delivering them to the
application.
So stop using precision.

These have been deprecated since API level 8 / 9. Plugins are deprecated
overall now, so there's no requirement for apps to call these any more.

Redesigned how ViewRootImpl delivers input events to views,
the IME and to native activities to fix several issues.
The prior change to make IME input event delegation use
InputChannels failed to take into account that InputMethodManager
is a singleton attached to the main looper whereas UI may be
attached to any looper. Consequently interactions with the
InputChannel might occur on the wrong thread. Fixed this
problem by checking the current thread and posting input
events or callbacks to the correct looper when necessary.
NativeActivity has also been broken for a while because the
default event handling logic for joysticks and touch navigation
was unable to dispatch events back into the native activity.
In particular, this meant that DPad synthesis from touch navigation
would not work in any native activity. The plan is to fix
this problem by passing all events through ViewRootImpl as usual
then forwarding them to native activity as needed. This should
greatly simplify IME pre-dispatch and system key handling
and make everything more robust overall.
Fixed issues related to when input events are synthesized.
In particular, added a more robust mechanism to ensure that
synthetic events are canceled appropriately when we discover
that events are no longer being resynthesized (because the
application or IME is handling or dropping them).
The new design is structured as a pipeline with a chain of
responsibility consisting of InputStage objects. Each InputStage
is responsible for some part of handling each input event
such as dispatching to the view hierarchy or to the IME.
As a stage processes an input event, it has the option of
finishing the event, forwarding the event to the next stage
or handling the event asynchronously. Some queueing logic
takes care to ensure that events are forwarded downstream in
the correct order even if they are handled out of order
by a given stage.
Cleaned up the InputMethodManager singleton initialization logic
to make it clearer that it must be attached to the main looper.
We don't actually need to pass this looper around.
Deleted the LatencyTimer class since no one uses it and we have
better ways of measuring latency these days using systrace.
Added a hidden helper to Looper to determine whether the current
thread is the indicated Looper thread.
Note: NativeActivity's IME dispatch is broken by this patch.
This will be fixed later in another patch.
