/**
* Native bindings to the ARB_vertex_buffer_object extension.
*
*
This extension defines an interface that allows various types of data (especially vertex array data) to be cached in high-performance graphics memory on
* the server, thereby increasing the rate of data transfers.
*
*
Chunks of data are encapsulated within "buffer objects", which conceptually are nothing more than arrays of bytes, just like any chunk of memory. An API
* is provided whereby applications can read from or write to buffers, either via the GL itself ({@link #glBufferDataARB BufferDataARB}, {@link #glBufferSubDataARB BufferSubDataARB},
* {@link #glGetBufferSubDataARB GetBufferSubDataARB}) or via a pointer to the memory.
*
*
The latter technique is known as "mapping" a buffer. When an application maps a buffer, it is given a pointer to the memory. When the application
* finishes reading from or writing to the memory, it is required to "unmap" the buffer before it is once again permitted to use that buffer as a GL data
* source or sink. Mapping often allows applications to eliminate an extra data copy otherwise required to access the buffer, thereby enhancing
* performance. In addition, requiring that applications unmap the buffer to use it as a data source or sink ensures that certain classes of latent
* synchronization bugs cannot occur.
*
*
Although this extension only defines hooks for buffer objects to be used with OpenGL's vertex array APIs, the API defined in this extension permits
* buffer objects to be used as either data sources or sinks for any GL command that takes a pointer as an argument. Normally, in the absence of this
* extension, a pointer passed into the GL is simply a pointer to the user's data. This extension defines a mechanism whereby this pointer is used not as a
* pointer to the data itself, but as an offset into a currently bound buffer object. The buffer object ID zero is reserved, and when buffer object zero is
* bound to a given target, the commands affected by that buffer binding behave normally. When a nonzero buffer ID is bound, then the pointer represents an
* offset.
*
*
In the case of vertex arrays, this extension defines not merely one binding for all attributes, but a separate binding for each individual attribute. As
* a result, applications can source their attributes from multiple buffers. An application might, for example, have a model with constant texture
* coordinates and variable geometry. The texture coordinates might be retrieved from a buffer object with the usage mode "STATIC_DRAW", indicating to the
* GL that the application does not expect to update the contents of the buffer frequently or even at all, while the vertices might be retrieved from a
* buffer object with the usage mode "STREAM_DRAW", indicating that the vertices will be updated on a regular basis.
*
*
In addition, a binding is defined by which applications can source index data (as used by {@link GL11#glDrawElements DrawElements}, {@link GL12#glDrawRangeElements DrawRangeElements}, and
* {@link GL14#glMultiDrawElements MultiDrawElements}) from a buffer object. On some platforms, this enables very large models to be rendered with no more than a few small commands
* to the graphics device.
*
*
It is expected that a future extension will allow sourcing pixel data from and writing pixel data to a buffer object.
*
*
Promoted to core in {@link GL15 OpenGL 1.5}.
