static GLuint	attr_size (const struct gl_client_array *array)

	Starts returning true slightly before the buffer fills, to ensure that there is sufficient room for any remaining vertices to finish off the prim:.

	Use a hashtable to attempt to identify recently-emitted vertices and avoid re-emitting them.
