dispatched through a unix pipe, so the API is compatible
with utils/Looper. see gui/DisplayEvent.h for more info.

The ScreenShot layer is now created hidden. The screenshot itself
is aquired during the transaction when the layer is made visible.
This guarantees the screenshot and the layer happen atomically
with respect to screen updates.

We now have mInvalidateRegion which holds the region to invalidate, it
can be set from any thread as long as mInvalidateLock is held. We use
fine-grained locking here because mInvalidateRegion can be set from anywhere,
in particular frmo HWC callbacks.

there was situations where SF's main loop would run (as if there was
an invalidate), but the dirty region was empty (so no new buffers
were retired). In this case we return early and don't swap, which
would cause drawing artifacts.

removed a test that could violate this guarantee. note that we
have no proof tha this ever happened, but consequences could be
hard lock-ups.
the code here was intended to track the region to update for displays
that can do partial update. the logic discarded the update entirely
if that region was empty. instead we just redraw the whole thing
(note that we should never be there with an empty region and retired
buffers though).

This change modifies SurfaceFlinger's screenshot behavior when a layer
with a protected buffer is visible. The previous behavior was to simply
fail the screenshot. The new behavior is to render the screenshot using
a placeholder texture where the protected buffer would have been.

Bug: 4981385
Simplify the orientation changing code path in the
WindowManager. Instead of the policy calling setRotation()
when the sensor determined orientation changes, it calls
updateRotation(), which figures everything out. For the most
part, the rotation actually passed to setRotation() was
more or less ignored and just added confusion, particularly
when handling deferred orientation changes.
Ensure that 180 degree rotations are disallowed even when
the application specifies SCREEN_ORIENTATION_SENSOR_*.
These rotations are only enabled when docked upside-down for
some reason or when the application specifies
SCREEN_ORIENTATION_FULL_SENSOR.
Ensure that special modes like HDMI connected, lid switch,
dock and rotation lock all cause the sensor to be ignored
even when the application asks for sensor-based orientation
changes. The sensor is not relevant in these modes because
some external factor (or the user) is determining the
preferred rotation.
Currently, applications can still override the preferred
rotation even when there are special modes in play that
might say otherwise. We could tweak this so that some
special modes trump application choices completely
(resulting in a letter-boxed application, perhaps).
I tested this sort of tweak (not included in the patch)
and it seems to work fine, including transitions between
applications with varying orientation.
Delete dead code related to animFlags.
Handle pausing/resuming orientation changes more precisely.
Ensure that a deferred orientation change is performed when
a drag completes, even if endDragLw() is not called because the
drag was aborted before the drop happened. We pause
the orientation change in register() and resume in unregister()
because those methods appear to always be called as needed.

we were not redrawing and/or clearing the FB properly when

We were not updating the h/w composer state when the buffer size
changed.
We also didn't update the h/w composer state when the transformation
matrix changed (which is related to the above issue, since it would
probably change when the buffer size changes).
Also moved updating the crop to setGeometry(), since we decided
that the "crop" change requires the GEOMETRY_CHANGED flag (ie:
not need to do this every frame)

we were using the "orientation" value instead of the

instance, and in some case ended up with a final "orientation"
that looked valid, but wasn't.

the rotation animation looked weird.

This change fixes the NATIVE_WINDOW_QUEUES_TO_WINDOW_COMPOSER query of
Surface and SurfaceTextureClient. Surface now uses the inherited
SurfaceTextureClient implementation of this query. SurfaceTextureClient

some other process).

SurfaceTextures::abandon on the layer's SurfaceTexture. This will cause

synchronous mode.

Bug: 5020874
This change fixes a bug where the window visibility would be computed
before any buffers were available, causing the window to be treated as
non-opaque. When the first buffer arrived, if both mCurrentOpacity and
the opacity determined by the buffer's format were 'opaque', a
recomputation of the opacity would not be done, and the window would
continue to be treated as non-opaque. SurfaceFlinger could then
unnecessarily draw fully occluded layers.
