/**
* Native bindings to the ARB_vertex_attrib_binding extension.
*
* OpenGL currently supports (at least) 16 vertex attributes and 16 vertex buffer bindings, with a fixed mapping between vertex attributes and vertex
* buffer bindings. This extension allows the application to change the mapping between attributes and bindings, which can make it more efficient to update
* vertex buffer bindings for interleaved vertex formats where many attributes share the same buffer.
*
* This extension also separates the vertex binding update from the vertex attribute format update, which saves applications the effort of redundantly
* specifying the same format state over and over.
*
* Conceptually, this extension splits the state for generic vertex attribute arrays into:
*
*
* - An array of vertex buffer binding points, each of which specifies:
*
*
* - a bound buffer object
* - a starting offset for the vertex attribute data in that buffer object
* - a stride used by all attributes using that binding point, and
* - a frequency divisor used by all attributes using that binding point.
*
* - An array of generic vertex attribute format information records, each of which specifies:
*
*
* - a reference to one of the new buffer binding points above
* - a component count and format, and a normalization flag for the attribute data, and
* - the offset of the attribute data relative to the base offset of each vertex found at the associated binding point.
*
*
*
* Promoted to core in {@link GL43 OpenGL 4.3}.
