we're seeing UI freezes when window updates and
composition are separated. for now we workaround this
by always doing a composition after window updates on
vsync. triple buffering is reenabled for performance.

with this changes, SF transactions are handled as soon as possible
but do not trigger updates. the update is delayed until the next
vsync.
this allows us to work much better without requiring triple-buffering.

--latency-clear [name]
clears the latency data for the specified layer or for
all layers if none is specified
--list
prints the list of all layers regardless of their visibility
Change-Id: I7c07ae020f838c173b98ee50f3fb3e93da78acbb
It is now possible to say:
dumpsys SurfaceFlinger --latency
to print latency information about all windows
dumpsys SurfaceFlinger --latency window-name
to print the latency stats of the specified window
for instance: dumpsys SurfaceFlinger --latency SurfaceView
The data consists of one line containing global stats, followed by
128 lines of tab separated timestamps in nanosecond.
The first line currently contains the refresh period in nanosecond.
Each 128 following line contains 3 timestamps, of respectively
the app draw time, the vsync timestamp just prior the call to set and
the timestamp of the call to set.

A LayerScreenshot is a special type of layer that contains a screenshot of
the screen acquired when its created. It works just like LayerDim.
Make sure to call compositionComplete() after rendering into a FBO.

when taking a screenshot, in particular, we could end up
with stale GL state when drawing LayerDim which resulted
in incortect rendering.

This change removes the dead code from SurfaceFlinger that resulted from

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.

This change makes SurfaceFlinger update a SurfaceTextureLayer's default
buffer size in response to a window resize even if the Layer is in fixed
size mode.

This change fixes the transform hint to use only the global display
transform rather than incorporating the transient layer-specific
transform used during animations.

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)

This change makes SurfaceFlinger always use the
GRALLOC_USAGE_HW_COMPOSER usage bit when allocating buffers that may be
passed to the HWComposer.

we were using the "orientation" value instead of the
real transform, which may contain arbitrary rotations for
instance, and in some case ended up with a final "orientation"
that looked valid, but wasn't.
this fixes a problem on devices with a h/w composer hal where
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
now queries SurfaceFlinger to determine whether buffers that are queued
to its ISurfaceTexture will be sent to SurfaceFlinger (as opposed to
some other process).

a wrong orientation would be briefly shown when
rotation the screen. this happened when the window manager
set a custom transformation and the h/w composer was used.
the custom transformation was applied twice in that case.

This change makes the Layer::onRemoved method call
SurfaceTextures::abandon on the layer's SurfaceTexture. This will cause
all client-initiated operations on the SurfaceTexture to fail. In
particular, this will result in an error on the client side, rather than
a deadlock when removing a layer that used a SurfaceTexture in
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.

Bug: 5057122
if the state transform didn't preserve rectangles, we
would still try to use h/w composer hal using the bounds
of the transformed rect, which isn't correct.
now we correctly fall back to composition.

This change alters the conditions under which the onFrameAvailable
callback gets called by the C++ SurfaceTexture class. The new behavior
is to call the callback whenever a frame gets queued that will be
visible to the buffer consumer. This means that buffers queued in
synchronous mode always trigger the callback, as those buffers will
remain pending until they are consumed. Buffers queued in asynchronous
mode will only trigger the callback if there was not previously an
unconsumed buffer pending.
The new behavior means that a consumer should perform a draw operation
exactly once for every onFrameAvailable call that it recieves. This
change also modifies SurfaceFlinger and the SurfaceTexture JNI to
support of the new behavior.
