This interface defines the set of calls that pipeline objects can use to pass on responsibility for drawing various basic geometric figures defined by explicit integer coordinates. Typically this interface will be used for communication when the coordinates of the rendering have been narrowed down to actual device pixels, or for communication of untransformed coordinates when the coordinates were specified using integers. This interface does not cover all of the rendering calls that are possible in Graphics since many of the rendering calls can be transformed into one or more variants of these calls.
