+ * This file implements the st_draw_vbo() function which is called from
+ * Mesa's VBO module. All point/line/triangle rendering is done through
+ * this function whether the user called glBegin/End, glDrawArrays,
+ * glDrawElements, glEvalMesh, or glCalList, etc.
+ *
+ * We basically convert the VBO's vertex attribute/array information into
+ * Gallium vertex state, bind the vertex buffer objects and call
+ * pipe->draw_elements(), pipe->draw_range_elements() or pipe->draw_arrays().
