/**

 *
 * Tests display list behavior for GL_ARB_draw_elements_base_vertex.
 *
 * From the GL_ARB_draw_elements_base_vertex spec:
 *
 *     "The commands
 *         void DrawElementsBaseVertex(enum mode, sizei count, enum type,
 *              void *indices, int basevertex);
 *
 *         void DrawRangeElementsBaseVertex(enum mode, uint start, uint end,
 *              sizei count, enum type, void *indices, int basevertex);
 *
 *         void DrawElementsInstancedBaseVertex(enum mode, sizei count,
 *              enum type, const void *indices, sizei primcount, int basevertex);
 *
 *      are equivalent to the commands with the same base name (without the
 *      "BaseVertex" suffix) except that the <i>th element transferred by
 *      the corresponding draw call will be taken from element
 *         <indices>[<i>] + <basevertex>"
 *
 *
 * From the GL_ARB_draw_instanced spec:
 *
 *     "The error INVALID_OPERATION is generated if
 *      DrawArraysInstancedARB or DrawElementsInstancedARB is called
 *      during display list compilation."
