+Vertex Elements
+===============
+
+This state controls format etc. of the input attributes contained
+in the pipe_vertex_buffer(s). There's one pipe_vertex_element array member
+for each input attribute.
+
+Members
+-------
+
+src_offset
+ The byte offset of the attribute in the buffer given by
+ vertex_buffer_index for the first vertex.
+instance_divisor
+ The instance data rate divisor, used for instancing.
+ 0 means this is per-vertex data, n means per-instance data used for
+ n consecutive instances (n > 0).
+vertex_buffer_index
+ The vertex buffer this attribute lives in. Several attributes may
+ live in the same vertex buffer.
+src_format
+ The format of the attribute data. One of the PIPE_FORMAT tokens.
