be6eac828f5af8b608c3fa6749330f1dcd6b6206 08-Dec-2009 Jack Palevich <jackpal@google.com> Implement Matrix Palette extension.

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.

be509c9c7de5929d014dfe6d45e71cc8454ede0f 07-May-2009 Jack Palevich <jackpal@google.com> 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.

a379585e6e3ff41db6d71a5cd0a0403931bc525d 24-Apr-2009 Jack Palevich <jackpal@google.com> 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.

27f8002e591b5c579f75b2580183b5d1c4219cd4 16-Apr-2009 Jack Palevich <jackpal@google.com> 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.
