-- | 'POLYGON_MODE_FILL_RECTANGLE_NV' specifies that polygons are rendered

-- the primitive if the sample location is inside the axis-aligned bounding
-- box of the triangle after projection. Note that the barycentric weights
-- used in attribute interpolation /can/ extend outside the range [0,1]
-- when these primitives are shaded. Special treatment is given to a sample
-- position on the boundary edge of the bounding box. In such a case, if
-- two rectangles lie on either side of a common edge (with identical
-- endpoints) on which a sample position lies, then exactly one of the
-- triangles /must/ produce a fragment that covers that sample during
-- rasterization.
--
-- Polygons rendered in 'POLYGON_MODE_FILL_RECTANGLE_NV' mode /may/ be
-- clipped by the frustum or by user clip planes. If clipping is applied,
-- the triangle is culled rather than clipped.
--
-- Area calculation and facingness are determined for
-- 'POLYGON_MODE_FILL_RECTANGLE_NV' mode using the triangle’s vertices.
