glEGLImageTargetRenderbufferOES() pass the wrapped EGLImage
to the implementation, rather than the unwrapped one.

with the GLThread.
We used to just set the mPaused state and return,
now we wait until the rendering thread signals
that it has noticed the change in pause state.
This makes Pause/Resume more consistent with
other UI-thread-to-GLThread event communication.
This change was made in the hope of fixing some
race conditions observed in monkey testing.
We now release the EGL context when pausing. This
is required to reduce the chance of running out of
contexts on devices which support a limited number
of active EGL contexts.
Someday we may implement a global EGL context
manager that will allow us to let EGL contexts
persist until another activity needs an EGL
context. But for now, without such a manager,
we take the conservative approach.
Separately, we now terminate EGL when
pausing on Sapphire. This is a requirement of the
Sapphire OpenGL driver.
Previously we imlpemented the standard semantics for
eglInitialize / eglTerminate, which are that
eglInitialize may be called any number of times,
but the first call to eglTerminate will terminate
the display.
Now we follow reference-countins semantics, which
means that eglTerminate will only terminate the
display when the reference count returns to zero.
This change allows EGL to be used by multiple
independently written modules in the same process.
(Otherwise there is no way for the independent
modules to coordinate their use of the display.)
We now distinguish EGL_CONTEXT_LOST errors from
other kinds of errors. We return "true" if
the swap completes successfully, "false" if
the swap fails due to EGL_CONTEXT_LOST, and
throw a RuntimeException if the swap fails due
to any other cause.
If eglSwapBuffers succeeds, we now avoid calling
eglGetError at all, which means we avoid clearing
any EGL errors that might already have been
pending before eglSwapBuffers is called.
This works around a bug in the
"Q3Dimension MSM7500" driver. That driver only
supports a single active EGLContext, so we must
release and restore the EGLContext when pausing
and unpausing.
Unfortunately the test for deciding whether to
release the context was inverted. We were
releasing the context on every device besides
the MSM7500 devices, which was a performance
drain, and we were not releasing the context on
the MSM7500, which meant the underlying driver
bug was not worked around.
Now we release the EGL context when pausing only
on the devices that have the bug.
A typo caused GL_AMBIENT_AND_DIFFUSE to only set the the ambient color.
Fix another typo which caused the viewer position to be wrong for
specular highlights.
Switch back to eye-space lighting, since there are still some issues
with some demos (San Angeles in particular).
The EGL context is now preserved when possible. Previously we would
destroy it whenever the EGL surface was destroyed. Preserving the
EGL context preserves loaded textures and VBO resources.
Duplicate ARCH_ARM_HAVE_TLS_REGISTER BoardConfig to proprocessor
HAVE_ARM_TLS_REGISTER define from Bionic's libc Android.mk to ensure that
OpenGL libraries (libEGL, libGLESv1_CM, libGLESv2, libGLES_android) use the
correct codepath in bionic_tls.h for accessing the TLS address
The build system does not honor user tags on apps,
and setting it is misleading.
This removes the confusion by making the makefiles
behave like they read.

Something happened to the line endings, adding
a blank line after most lines of text. I
repaired the damage, but in the process some
blank lines have been added / removed.
The problem was a black first frame when creating a surface, or a
garbage frame when the surface was resized.
The cause was lack of synchronization between the render thread and the
UI thread. The UI thread would typically return before the render thread
had a chance to draw its first frame.
The fix was to make the UI thread wait until at least one frame had been
rendered by the rendering thread.
The waiting is done in the surfaceChanged method because we know
that surfaceChanged will be called in both the surface created
and surface changed cases.

* commit '3608891b83af9fbd1af9b9a411f2a90e52353ff8':
Add a Java API for OpenGL ES 2.0.
Adds support for formerly-unimplemented methods:
glCurrentPaletteMatrixOES
glLoadPaletteFromModelViewMatrixOES
glMatrixIndexPointerOES
glWeightPointerOES
The bulk of the changes are related to implementing the two PointerOES
methods, which are implemented pretty much the same way as the existing
Pointer methods were implemented.
This change also changes the way glPointSizePointerOES is implemented,
making it act like all the other Pointer methods. (Previously it was
not handling non-direct-buffer arguments correctly.)
Fixes bug 2308625 "Support matrix palette skinning
in JSR239 and related APIs"
Also updated GLLogWraper to fix two bugs in GLLogWrapper that were
discovered while testing matrix palette skinning support:
a) Handle trying to print the contents of null-but-enabled buffers.
(It's not legal to draw with null-but-enabled buffers, and
in fact some OpenGL drivers will crash if you try to render in this
state, but there's no reason the GLLogWrapper should crash while trying
to debug this situation.
b) Don't read off the end of a vertex buffer with non-zero position when
printing the entire contents of the vertex buffer. Now we only print from
the current position to the end of the buffer.
Provide a new method, GLSurfaceView.setEGLContextClientVersion. Clients
call this method to define which level of OpenGL ES support they want.
This method only affects the default behavior of GLSurfaceView. If clients
have supplied their own EGLContextFactory or EGLConfigChooser then they
are on their own if they want to create an OpenGL ES 2.0 context.
This API is currently hidden.
Update the gl2_java test to use this new API.
Update the gl2_java test's AndroidManifest.xml file to indicate that
it requires OpenGL ES 2.0.
