 * NAME:        RE_OGLVertexArrayList.h ( RE Library, C++)
 *
 * COMMENTS:
 *      Implements an OpenGL Vertex Array Object, which is a collection of
 *      vertex buffer bindings to various attribute types (vertex, color,
 *      normal...)
 *
 *      Note that this object is not shared with other shared contexts. It only
 *      exists in the OpenGL context that created it.
