routines affected by these extensions. New variants take long as
argument instead of Buffer for void*. For these routines as well as
the original versions, must check whether VBO/PBO is active or
inactive. Added check to affected methods to guarantee they are not
called within glBegin/glEnd pairs (which in most, if not all, cases is
already a requirement) to avoid tracking OpenGL state manually. Added
new JavaPrologue and JavaEpilogue commands to JavaConfiguration with
optional signatures to differentiate overloaded methods. Added
BufferObjectKind command to GLConfiguration which builds on
JavaPrologue support. Deleted BufferUtils.bufferOffset() and
associated native code.
In order to reduce the number of extension routines, added
IgnoreExtension directives for all extensions folded into OpenGL 1.1,
1.2 and 1.3 specifications; this means that if the core OpenGL version
is less than 1.3 then these extensions are effectively unavailable.
Updated demos for both new VBO/PBO API variants as well as extensions
folded into core.

only package specified by the JSR is "javax.media.opengl". The utility
package com.sun.opengl.utils is Sun-specific and optional. The Cg
binding has been moved into com.sun.opengl.cg. Moved Animator and
FPSAnimator to com.sun.opengl.utils. Updated and tested demos with new
source code locations.

match desired new code generation style of mapping void* to Buffer and
to support non-direct Buffers. Removed expansion of void* to multiple
primitive array types. Primitive-type C pointers (such as int*) are
now exposed as IntBuffer and (optionally) int[], if NioDirectOnly has
not been specified. The int[] variant is a simple wrapper around the
indirect buffer implementation. If desired, expansion of void* to
other array types could be layered on this new support.
Rewrote and simplified expandMethodBinding and split up creation of
emitters into generatePublicEmitters and generatePrivateEmitters.
Deleted JavaMethodBindingImplEmitter and CMethodBindingImplEmitter and
folded their functionality into their superclasses, controlled under
flags, which makes it more straightforward to tweak a given emitter to
produce correct glue code. Restructured OpenGL-specific
JavaGLPAWrapperEmitter and CGLPAWrapperEmitter and how they are
created by the GLEmitter; these classes are now much simpler than
before.
Changed how data types are passed from MethodBindings to Emitters.
Generally only two MethodBindings will be created, one which maps
types like int* to IntBuffer and one which maps it to int[]. The
version taking Buffers will be the only one for which glue code will
be generated; the one taking int[] will call the native code for the
indirect buffer case for the one taking Buffers. Compound types
(representing C structs) and compound type arrays (represending arrays
of C structs) are no longer mapped to NIO ByteBuffers and arrays of
NIO ByteBuffers by the MethodBinding; erasure and lowering of types is
now handled by the Emitters, to preserve more type information during
the code generation process. It is unclear whether this is in the end
a simplification or just pushing code around, but it does help reduce
confusion over the number of MethodBindings floating around in the
system and what purpose they served.
Restructured cure JOGL code and demos to work with new APIs, in
particular new glTexImage*D, glDrawElements, and glReadPixels Buffer
arguments. Fixed performance problem in new Animator which occurred
with VertexArrayRange demo. Added new gluPickMatrix entry point to be
able to implement NIO variant in generated signatures.
Some further simplifications of the new code may be possible (i.e.,
some new flags in JavaMethodBindingEmitter and MethodBinding removed)
and it is possible more unused code remains to be deleted. As it
stands the new GL.java is significantly smaller than before, as all of
the expansions of void* to primitive arrays are gone, several areas of
GlueGen are easier to understand, and while some functionality has
been lost, the autogenerated APIs are basically in the final form
specified by JSR-231.
Tested with the JOGL demos on Windows and Linux.

Ported all demos to new API. Temporarily added back in GLU entry
points taking primitive arrays as the underlying APIs (in particular,
glTexImage2D) do not yet support non-direct Buffers. Changed C code
generation to only add in array offset if array is non-null. Fixed bug
in GLU tesselator demo's vertex callback.
