After a HWC set, each SurfaceFlinger Layer retrieves the release fence
HWC returned and gives it to the layer's SurfaceTexture. The
SurfaceTexture accumulates the fences into a merged fence until the
next updateTexImage, then passes the merged fence to the BufferQueue
in releaseBuffer.
In a follow-on change, BufferQueue will return the fence along with
the buffer slot in dequeueBuffer. For now, dequeueBuffer waits for the
fence to signal before returning.
The releaseFence default value for BufferQueue::releaseBuffer() is
temporary to avoid transient build breaks with a multi-project
checkin. It'll disappear in the next change.

The desc.txt file can now mark parts as 'must finish cleanly' by using
'c' as the part line prefix rather than 'p'. If so indicated, if the
bootanimation is asked to quit it will do so only after waiting to
finish that part.
I considered either making init.c service killing smarter or promoting
bootanim to be a bindable service with a requestExit method. However,
these changes are probably too big/risky given our ship date. So
I used a property as a mailbox between SurfaceFlinger and bootanim.

HWComposer must abstract the HWC HAL entirely, so that the
HAL can continue to evolve (and break binary compatibility)
without breaking SurfaceFlinger. The HWC data structure had
leaked outside of HWComposer, this is now fixed.
We now have an abstract interface that provide all the
needed functionality, HWCompose provides concrete
implementations of it based on the the HWC version.

SurfaceFlinger will no longer directly synchronize with early suspend.
Instead, PowerManagerService will synchronize with SurfaceFlinger to
ensure that a black frame has been drawn on the display, and then
trigger all early suspend handlers.

This change adds a crop rectangle specified in window coordinates to the layer
state. The all window pixels outside this crop rectangle are treated as though
they were fully transparent. This change also adds the plumbing necessary for
WindowManager to set that crop.

this seems to hurt performance on some GPU. this change
might negatively affect performance on other GPUs though, but
probably in less time-sensitive cases. If this becomes a
problem it might become necessary to pre-clip the geometry
(so that we don't have to use glScissor).
This improves the rotation animation quite a bit.

this optimization didn't improve performance and in fact
seemed to hurt more than anything else. it also made
things a lot more complex as it introduced edges cases
when switching to/from h/w composer.

surfaceflinger will now handle each surface post
as soon as possible and handle the composition
itself at VSYNC time as usual.
Change-Id: I6b1ae33fd56062d86e5419ebab8def0ca5803fbf
this prevents the GPU from running when composition
is fully handled by overlays. this should improve
animations a bit.

SF could end-up in an infinite crash-loop during startup if it
was stopped while the screen was off. This happened because
the thread that manages screen blanking was started before
other important pieces of SF were initialized.

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.

In some situations SF would mark a window as "has a pending update"
but would never process that update because the window is not
visible (fully transparent, hidden by another window, etc...), this
window would then be "stuck" until some other window updated.
Change-Id: Ifa18a9aef3a53f2593b473556702688ae62d9503
recent changes in SF introduced a hang where some windows would
stop being refreshed.
This is an attemp to fix that.
Change-Id: I6aa32ac0d6f1c0a6aea8f6195825dc4f4e6f93f9
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

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.

Some implementations of NPOT, particular those derived from core
GLES2, require the wrap mode to be CLAMP_TO_EDGE. Set the required
wrap mode for the screenshot texture so it passes the completeness
check.
