2a9fa89643 Don't build display lists for views with a layer.
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.

f504a2fa14 Correctly implement the CLEAR xfermode.
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.

aa6c24c21c New widget: TextureView
Bug #4343984

TextureView can be used to render media content (video, OpenGL,
RenderScript) inside a View.

The key difference with SurfaceView is that TextureView does
not create a new Surface. This gives the ability to seamlessly
transform, animate, fade, etc. a TextureView, which was hard
if not impossible to do with a SurfaceView.
A TextureView also interacts perfectly with ScrollView,
ListView, etc. It allows application to embed media content
in a much more flexible way than before.

For instance, to render the camera preview at 50% opacity,
all you need to do is the following:

mTextureView.setAlpha(0.5f);
Camera c = Camera.open();
c.setPreviewTexture(mTextureView.getSurfaceTexture());
c.startPreview();

TextureView uses a SurfaceTexture to get the job done. More
APIs are required to make it easy to create OpenGL contexts
for a TextureView. It can currently be done with a bit of
JNI code.

8a5cc92a15 Fix various hw-accelerated line/point bugs
All accelerated lines are now rendered as quads. Hairlines used to
be rendered as GL_LINES, but these lines don't render the same as our
non-accelerated lines, so we're using quads for everything. Also, fixed
a bug in the way that we were offsetting quads (and not offseting points)
to ensure that our lines/points actuall start on the same pixels as
Skia's.

09b7c91de7 Allocate layers from the layers pool.
Bug #3413433

This change will be beneficial to Launcher to avoid hiccups when
swiping pages of icons. When a layer is discarded, it is kept
in the layers pool instead of being destroyed right away. This
favors memory reuse over allocations.
