+/** \file pipeline_stats_vert_adj.c
+ *
+ * This test verifies that the vertex shader related tokens of
+ * ARB_pipeline_statistics_query() work as expected. Much of this was derived
+ * from ignore-adjacent-vertices.c
+ *
+ * 10.11
+ * In case of primitive types with adjacency information (see sections 10.1.11
+ * through 10.1.14) only the vertices belonging to the main primitive are
+ * counted but not the adjacent vertices. In case of line loop primitives
+ * implementations are allowed to count the first vertex twice for the
+ * purposes of VERTICES_SUBMITTED_ARB queries. Additionally, vertices
+ * corresponding to incomplete primitives may or may not be counted.
+ *
+ * I read this as: the only definite thing we can test across implementation is
+ * discarding adjacent vertices.
