b3a5352b96 Add a Java API for OpenGL ES 2.0.
Currently this API is hidden.

Add a test program.

6eedc8d3b5 Fix bug 1856713 gl Pointer functions should use Buffer position
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.

d373c6348a remove the gl{Vertex|Color|TexCoord|Normal}PointerBounds() "extension" fro eglext.h 2009-05-08 17:18:55 -07:00

593f203ba3 Fix automatically generated code for glGet
Remove include of an internal agl header file. We should not depend on any implementation details
of our software renderer, since they may not be correct if another renderer is used.
Fix glGet number-of-elements logic for GL_FOG_COLOR GL_LIGHT_MODEL_AMBIENT,
and GL_COMPRESSED_TEXTURE_FORMATS.

3327d6c5ac Enable static Java APIs for OpenGL ES 1.1 extensions.
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.

427f585f72 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.
