Rasterized points, lines 40and triangles are compared to reference, and a deviation of 1 pixel in 41position is allowed. 42 43Fill rules are tested using additive blend so that pixels on shared 44triangle edges are filled exactly once. Because exact fill rules are 45not specified, reference rasterizer uses all valid combinations of 46LEFT, RIGHT, TOP and BOTTOM. 47 48Value interpolation is tested for lines and triangles with 49vertex-specific colors, small deviation in interpolated color is allowed. 50 51Multisample rasterization is tested with points, lines and triangles. 52Because sampling pattern is unknown, deviation in produced colors is 53allowed. 54
