Drawing System Upgrading: The Q2 is available as a series—the Q Series—in the same
way as the SuperH, enabling the user to select the most appropriate Q2 and SuperH models for his
application. The user's drawing system can also be upgraded as necessary by changing the Q2 or
SuperH combination.
Consistency of Application Interface: The Q2's carefully selected drawing commands are
of four kinds: four-vertex surface drawing, line drawing, work surface drawing, and work line
drawing. This makes it possible to reduce the parts dependent upon drawing commands within an
application, and so achieve a more consistent interface between applications.
