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.)
A typo caused GL_AMBIENT_AND_DIFFUSE to only set the the ambient color.

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.

in the case where we fade a 32-bits surface (ie: GL_MODULATE w/ a,a,a,a + blending),

Instead of using a different function pointer table for ES 1.x and ES 2.x,
we use a single one that is the union (sort|uniq) of both tables. Two
instances of this table are initialized with pointers to GL ES 1.x and GL ES 2.x
entry-points.
When a context is created, we store its version number and when it is bound to a
thread we set the approruiate table based on the stored version.
This introduce no penalty while dispatching gl calls to the right API version.

fix [2168531] have software-only gralloc buffer side-step the HAL
fix [2167050] glTexImage2D code path buggy in SurfaceFlinger
When EGLImage extension is not available, SurfaceFlinger will fallback to using
glTexImage2D and glTexSubImage2D instead, which requires 50% more memory and an
extra copy. However this code path has never been exercised and had some bugs
which this patch fix.
Mainly the scale factor wasn't computed right when falling back on glDrawElements.
We also fallback to this mode of operation if a buffer doesn't have the adequate
usage bits for EGLImage usage.
This changes only code that is currently not executed. Some refactoring was needed to
keep the change clean. This doesn't change anything functionaly.
executables have calls to some shared libraries without explicitly linking
them. Currently it works as linker links these libraries via dependencies of
other libraries. This is fragile and not the right thing to do.

Use EGLUtils::selectConfigForNativeWindow to select a legitimate
configuration. (Before now we had been selecting an incorrect
configuration, but the older drivers let us get away with it.)
Converted the source to C++ so we can call selectConfigForNativeWindow.
this change fixes the lifetime mgt of EGLSurface, EGLContext and EGLImageKHR in the EGL wrapper.
EGLDisplay is still somewhat bogus and libagl's EGL is still incorrect.
The idea of the change is that EGL objects are put in a list when created and removed when destroyed.
Before each use, we first verify if the object is in the list and if so a reference is taken and kept
for the scope of the whole EGL API being called, if not, an error is returned.
Upon object destruction, the object is simply marked as "terminated" (this is not protected by a lock
because it doesn't really matter). This flag is only used to deny access to the object by other APIs
while it's still valid (for instance current or being used by another function in another thread).
A reference is also removed and the object can then actually be destroyed when going out of scope.
refactored the code so that:
- EGL APIs that can be called before or after eglInitialize() will work by loading the drivers first
- make eglGetDisplay() a lot more efficient
- make sure that EGL drivers are loaded in a thread-safe way
- don't unload the drivers upon calling eglTerminate(), they're now never unloaded, since there is no safe way to do it (some thread could be running)
- updated our EGL version to 1.4
- return better error codes if errors happen during initialization

Revert "SurfaceFlinger will now allocate buffers based on the usage specified by the clients. This allows to allocate the right kind of buffer automatically, without having the user to specify anything."
This change makes SurfaceHolder.setType(GPU) obsolete (it's now ignored).
Added an API to android_native_window_t to allow extending the functionality without ever breaking binary compatibility. This is used to implement the new set_usage() API. This API needs to be called by software renderers because the default is to use usage flags suitable for h/w.
there was several issues:
- when a surface was made non-current, the last frame wasn't shown and the buffer could stay locked
- when a surface was made current the 2nd time, it would not dequeue a new buffer
now, queue/dequeue are done when the surface is made current.
for this to work, a new query() hook had to be added on android_native_window_t, it allows to retrieve some attributes of a window (currently only width and height).

Adding missing callback onJsConfirm to dismiss any confirmation dialogs
fix a bug in GL lighting where the specular component could be ommited when vertex material was disabled.
This bug was introduced when lighting computations was changed from eye-space to object-space.
The light position need to be transformed back to object-space each time the modelview matrix changes which requires us to compute the inverse of the modelview matrix. This computation was done with the assumption that normals where transformed (which was the case when the computation was made in eye-space), however, normals only require the inverse of the upper 3x3 matrix while transforming positions requires the inverse of the whole matrix.
This caused the interesting behavior that lights were more-or-less transformed properly, but not translated at all, which caused improper lighting with directional lights in particular.
There was also another smaller bug affecting directional lights: when vertices are read, only the active component are read, the other ones are ignored, later, the transformation operations are set up to ignore the unset values, howver, in the case of lighting, we use the vertex in object space (that is, before it is transformed), and therefore were using uninitalized values; in particular w.

JSR239 and android.opengl gl Pointer functions (glColorPointer, etc.)
now respect the current setting of the Buffer position.
This fixes a regression introduced when we started requiring the
Buffers passed to the Pointer functions to be direct Buffers.
This was always a documented restriction, but was not enforced by the runtime until now.
Until now, if you passed in some other kind of buffer, it would sometimes work, and
sometimes fail. The failures happened when the Java VM moved the buffer data while
OpenGL was still holding a pointer to it.
Now we throw an exception rather than leaving the system in a potentially bad state.
ANDROID_swap_rectangle allows to specify the rectangle affected by eglSwapBuffers(), anything outside of this rectangle is unchanged. in particular EGL_BUFFER_DESTROYED only applies to that rectangle. This extension as well as EGL_BUFFER_PRESERVED allow major optimizations on surfaceflinger, which can redraw only the dirty area during compositing.
However, ANDROID_swap_rectangle allows further optimizations in EGL by reducing the amount of copy-back needed. ANDROID_swap_rectangle is particularily important for software implementations.
Remove include of an internal agl header file. We should not depend on any implementation details

- Currently the lock/unlock path is naive and is done for each drawing operation (glDrawElements and glDrawArrays). this should be improved eventually.
- factor all the lock/unlock code in SurfaceBuffer.
- fixed "showupdate" so it works even when we don't have preserving eglSwapBuffers().
- improved the situation with the dirty-region and fixed a problem that caused GL apps to not update.
- make use of LightRefBase() where needed, instead of duplicating its implementation
- add LightRefBase::getStrongCount()
- renamed EGLNativeWindowSurface.cpp to FramebufferNativeWindow.cpp
- disabled copybits test, since it clashes with the new gralloc api
- Camera/Video will be fixed later when we rework the overlay apis
This is just plumbing. The Java APIs existed already, but there were no C APIs to hook the Java APIs
up to. Now there are C APIs, so we can call them.
Of course, whether or not the C APIs actually work when you call them depend upon the
capabilities of the active OpenGL driver, which must be checked at run time.
Also, while we're here, make the glGetString method static. It was always supposed to be static,
but was accidentally implemented as non-static, because the code was copied from the non-static
OpenGL ES classes.
This adds a static OpenGL ES API.
Here are the three commit messages for the original changes:
Clean up trivial Eclipse warnings and fix whitespace.
Added @Override to overridden methods.
Removed unused imports.
Converted tabs to spaces.
Removed \r characters from end-of-lines.
Add .gitignore file to ignore the .class files that are
generated when the "gen" script is run.
This is the 2nd commit message:
Improve glgen
+ gen script is really a bash script rather than a sh script,
so declare that to be true. (For example, it uses pushd,
which is a part of bash, but not a part of sh. Not sure
how this worked until now. Possibly gen was only run in
environments where /bin/sh was really bash.
+ Check the results of the java compile of the code generator,
and abort the script if the compile fails.
+ Turn on the bash shell option that guards against using
uninitialized variables in the script.
+ Remove the generated class files.
Refactor JniCodeEmitter into two classes: a general-purpose
JniCodeEmitter and a specific Jsr239CodeEmitter. The hope is
to use JniCodeEmitter as a base for emitting static OpenGL ES
bindings.
This is the 3rd commit message:
Add an Android-specific static OpenGL ES 1.1 Java API.
This change adds four new public classes that expose a static OpenGL ES 1.1 API:
android.opengl.GLES10
android.opengl.GLES10Ext
android.opengl.GLES11
android.opengl.GLES11Ext
Benefits:
+ The static API is slightly faster (1% to 4%) than the existing Interface based JSR239 API.
+ The static API is similar to the C API, which should make it easier to import C-based
example code.
+ The static API provides a clear path for adding new OpenGL ES 1.1 extensions
and OpenGL ES 2.0 APIs, neither of which currently have a JSR standard.
Example:
import static android.opengl.GLES10.*;
...
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
Note that it is possible to mix-and-match calls to both the static and JSR239 APIs.
This works because neither API maintains state. They both call through to the same underlying
C OpenGL ES APIs.
Implementation details:
This change enhances the "glgen" "gen" script to generate both the original JSR239 and
new static OpenGL ES APIs. The contents of the generated JSR239 classes remained the same as before,
so there is no need to check in new versions of the generated JSR239 classes.
As part of this work the gen script was updated to be somewhat more robust, and to
work with git instead of perforce. The script prints out commands to git add the generated files,
but leaves it up to the script runner to actually execute those commands.
