Without that lock, there is a chance of race condition
where while composing a specific index, requestBuf with
the same index can be executed and touch the
same data that is being used in initEglImage.
(e.g. dirty flag in texture)
SW renderer of Stagefright reaches loadTexture() to draw image.
The first time loadTexture() is called, it just initializes OGL
texture, then returns. Thus, the first time call doesn't draw.
This patch fixes to move on to draw stage after the initialization.

37c2a37 fix [3408713] Dialog window invisible sometimes
It looks like there is a surface leak, it's unclear where it is.
Without those reverts, this would cause a leak of the associated buffers
which is far more problematic. this change might hide the surface leak.

Bug: 3513017
Change-Id: Ia13ed8c9cdcb1f484e177cdcaff687e7c88a10c3
When some Surfaces are overlapping and one of them changed to
transparent or opaque, the back Surfaces should appear or
disappear. This patch calls SurfaceFlinger::computeVisibleRegions()
to re-calculate region of each Surface to implement the behavior.

Generally we never want to lock a buffer for write access if it is at
the "head" on the surfaceflinger side. The only exception (1) is when
the buffer is not currently in use AND there is at least one queued
buffer -- in which case, SurfaceFlinger will never use said buffer
anymore, because on the next composition around, it will be able to
retire the first queued buffer.
The logic above relies on SurfaceFlinger always retiring
and locking a buffer before composition -- unfortunately this
didn't happen during a screenshot.
This could leave us in a situation where a buffer is locked by the
application for write, and used by SurfaceFlinger for texturing,
causing a hang.
Here, we fix this issue by never assuming the exception (1), it was
intended as an optimization allowing ANativeWindow::lockBuffer() to
return sooner and was justified when most of SF composition was
done in software. The actual buffer locking is now ensured by
gralloc. We could have handled screenshots in a similar way to
a regular composition, but it could have caused glitches on screen,
essentially, taking a screenshot could cause to skip a frame.
now that we removed the notion of a "inUse" buffer in surfaceflinger
a lot of code can be simplified / removed.
noteworthy, the whole concept of "unlockClient" wrt. "compositionComplete"
is also gone.
We used to guarantee that a layer in SurfaceFlinger would never be
destroyed before all references (to its ISurface) on the client
side would be released. At some point, this guarantee got
relaxed to allow to free gralloc resources sooner. This last
change was incorrect, because:
- in implementations with reference-counting the gralloc resources
wouldn't be released anyways, until all the mapping were gone
- in implementations without ref counting, the client side
would most likely crash or do something bad
- it also caused the SharedBufferStack slot to be reallocated
to another surface, which could be problematic if the client
continued to use the surface after the window manager destroyed it.
So, we essentially reinstate the guarantee that layers won't be
destroyed until after all references to their ISurface are
released.
NOTE: This doesn't entirely fix 3306150 because there is another
problem there where the Browser continues to use a surface after it
has been destroyed.
also improve SurfaceFlinger 'dumpsys' log
list the purgatory, which shows windows that have been closed,
but for which the client still has references.
we were not clearing the screen entirely, which caused garbage when
the screen wasn't entirely covered by windows.

we make sure to call compositionComplete after everytime we do
composition with the GPU (even for the screenshot case), which is
where the buffer locks are released.

This is a poor's man precursor to the h/w composer HAL.
Basically we detect when a window is full screen and in
that case we bypass surfaceflinger's composition step, which
yields to much improved performance.

mFixedSize was never set, this bug was introduced during some "cleanup", in
practice this could cause some issues when a fixed-size buffer was used and
the window was resized.
Layer::drawForSreenShot() had a typo that had no effect.
mFixedSize was used to determine if filtering was needed, which was a bit too
conservative and created a dependency between filtering and "fixed size" states
which should exist.
Now we enable filtering based on the size of the buffer vs. the size of the layer.

some of these failures are not fatal and even expected in some cases
so they should not emit a dump in the log in those cases.

Two bugs were counter acting each other.
- rotation matrices are on the left-hand side of multiplies
- the transform of the overlay is applied before that of the layer

The problem wasn't in the multiply operator, but rather in the code
that built the transform from the HAL bitmask.
We now use the multiply operator to build the Transform from the bitmask,
which guarantees, it'll always be correct.
Also added a simple test for Transform.

There is now a parameter that controls wether the ON and/or OFF animation are

HOWEVER, 3096779 is not 100% fixed in the case where we're doing the animation
because there is a race, where SF doesn't wait (b/c it doesn't know) for the
framework to have redrawn the lockscreen.
