when areas of the FB are undefined (transparent windows on top of
nothing), we clear those areas before composition.
however, it makes no sense to do this when the FB is not in use
(case where hwc handles all layers)

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 need to clear the whole framebuffer in that situation because
we can't trust the content of the FB when partial (fb preserving)
updates are used.

lockPageFlip to get the opaqueness for the new buffer before
mActiveBuffer was updated.

we were not redrawing and/or clearing the FB properly when
hwc moved a layer from/to FB to/from OVERLAY.
In these cases we needed to expand the dirty region to include
the layer that changed mode.
Also split composeSurfaces() which was becoming quite large.
Change-Id: Id6fa1acfc4ff694037fddf7efd037a4405732073
this happened when the overlays were in use, since the animation
is rendered in the FB and the FB is not used.
we now have a way to turn hwc off temporarily.

these were due to the "preserve backbuffer" optimization
interfering with hw composer. basically the screen needed
to be redrawn in the areas that move from GL to
overlay.

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).

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 SurfaceFlinger's SurfaceTexture objects default to
async mode whenever a camera or video decoder connects. This behavior
can be disabled by #defining NEVER_DEFAULT_TO_ASYNC_MODE.

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.

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.
