SurfaceFlinger was rendering dark purple for secure content, which
showed up when we took a screen shot for the orientation change
animation.  Use black instead.

Merge "Change API from flush(handle) to flush(). Call flush on all active sensors in the given SensorEventConnection." into klp-dev

Since the latency was introduced to avoid egregious errors during
resampling, remove it when we aren't resampling.

This change removes the wakeup latency compensation from the software-generated
vsync events.  Choreographer can't handle timestamps in the future, so don't
aim for early wake-ups with the expectation that the actual wake-up will be
late.

The screen capture code wasn't waiting for the render to finish,
so sometimes you'd see an empty or partial image.

Bug 11131777

Change-Id: Ic64087322ce3bb15bb5f4fb1eb07579880fe6197

This change adds the DispSync class, which models the hardware vsync event
times to allow vsync event callbacks to be done at an arbitrary phase offset
from the hardware vsync.  This can be used to reduce the minimum latency from
Choreographer wake-up to on-screen image presentation.

This lets audioflinger assign blame for wakelocks to a single uid.
Currently this is only used for recording wakelocks.

Change-Id: If76e9fb055103bad0db7e6c16487532671573149

This change makes GLConsumer use the EGL_ANDROID_image_crop extension when
available on a device.  The crop rectangle is passed to the EGL driver when
creating EGLImages, allowing the crop to be performed by the driver rather than
using the texture transform matrix.

In GLES-only mode, we don't have the outbuf acquire fence until after
GLES composition is done for the frame. We were setting the fence in
HWC's state immediately after dequeueing the buffer from the consumer,
before GLES had started. This fence got passed through HWC and on to
the consumer, so the consumer was reading the buffer before GLES was
done writing to it.

Now we update HWC's state just before set(), when we know we have the
right fence.

a layer need to be considered NOT opaque if it has a
plane-alpha.

When there are no window layers for a display, SurfaceFlinger clears
the undefined region using GLES. Some of the places that check for
GLES composition weren't considering this special case, in particular:

- We were skipping the eglSwapBuffers() on these frames.
- We were putting VirtualDisplaySurface in HWC-only composition mode.

This change centralizes the logic for this special case.

This fixes two bugs introduced by
  Change-Id: Ia8cc084c02a0e3de910def024da8a08d02bbd89d

(a) There is no invalid EGLConfig value, in particular zero is valid.
    Checking return values of eglGetConfigs and eglChooseConfig is the
    only way to determine success.
(b) The "simple" EGLConfig query used as the emulator fallback should
    not include EGL_RECORDABLE; the emulator doesn't have it.
