Some views (such as ImageView and TextView) handle non-opaque alpha
values directly. This was originally an optimization, but we can handle it faster
in many cases without this optimization when DisplayList properties are enabled.
Basically, if a view has non-overlapping rendering, we set the alpha value directly
on the renderer (the equivalent of setting it on the Paint object) and draw each
primitive with that alpha value. Doing it this way avoids re-creating DisplayLists
while getting the same speedup that onSetAlpha() used to get pre-DisplayList properties.

Re-enabling DisplayList properties last week caused some app
errors due to the way that some transforms were being handled (specifically,
those coming from the old Animations and ViewGroup's childStaticTransformation
field). This change pushes *all* transform/alpha data from View.draw() into
the view's DisplayList, making DisplayLists more encapsulated (and correct).

When a drawPath command is recorded in a display list, a copy of the
source path is made to preserve against possible modifications of the
said source path. Copies are discarded when a display list is cleared,
which usually happens on invalidate(). This means that even if a path
is never modified, the texture generated to draw it on screen is
destroyed every time an invalidate() is issued. This change fixes this
problem by introducing a reference to the source path in the copy.
If both the copy and the source path have the same genID, they are
the same path and can share the same texture.

Bug #5553515
The People app is forcing ACTV to show the IME which had the side effect
of showing the drop down popup. ACTV was unfortunately not ready to show
the drop down if the filtering resulted in no results. Doing so was putting
ACTV in a weird state that in turn caused a window to be leaked and really
bad behavior to occur in the lower graphics levels.

This adds basic support for clip regions. It is currently disabled at compile
time. Enabling clip regions will require setting up a stencil buffer.

The render threat is likely to break your application if you initiate it.
As such it must be explicitely requested using the following meta-data
tag in your manifest's application tag:
<meta-data android:name="android.graphics.renderThread" android:value="true" />

This could cause the draw() code of views to be invoked too often
or worse, called with the wrong canvas. For instance, a view backed
by a software layer could get its draw() method called to record a
display list. Using a software layer is the recommended way to use
drawing operations not supported in hardware. Since we would
sometimes call the draw() method with the hardware backend anyway,
the app could crash by executing an unsupported operation.

If returns true, the SurfaceTexture will be released by TextureView.
If returns false, the client needs to release the SurfaceTexture.

To profile the looper, run the following command:
adb shell am profile looper start <process> <file>
adb shell am profile looper stop <process>

This method is invoked by TextureView.getBitmap() and failures must be
caught to avoid leaving the GL context in a potentially bad state.

This is needed for Renderscript and it also makes implementations
of TextureView cleaner. This change also hooks up the onSurfaceTextureSizeCHanged()
callback whenever the view size changes.

The previous implementation was using glBlendFunc with the parameters
GL_ZERO/GL_ZERO which doesn't work for text, paths and other alpha
sources (anti-aliasing.) The correct implementation is GL_ZERO/
GL_ONE_MINUS_SRC_ALPHA.
