/* param.h	Definitions for primitive objects in Workstation Graphics
 *		Architecture
 *
 *	Each object has two definitions.  The more human-readable one
 *	has "reasonable" definitions, the one beginning with a_ expresses
 *	the structure as an array of shorts so that the C compiler doesn't
 *	move it around for silly alignment reasons.
