Render supports two modes of precision when rendering trapezoids. Precise specifies points sampling on a 15x17 grid, ala pixman. Imprecise allows the driver more freedom in the methods used, which may be more amenable to acceleration. Choose to use the imprecise mode by default, but still allow users to force the more rigidly specified precision by changing the antialias mode.
