22 + dEQP-GLES2.functional.rasterization.*
25 + Primitive rasterization
29 + Individual triangles, triangle strips and triangle fans
30 + Varying interpolation in all primitives
31 + Projected (w != 1) and non-projected (w == 1) coordinates
32 + Fill rule verification
34 + Multisample rasterization
38 This test set compares images rendered by a reference software
39 rasterizer to images rendered by the target. Rasterized points, lines
40 and triangles are compared to reference, and a deviation of 1 pixel in
43 Fill rules are tested using additive blend so that pixels on shared
44 triangle edges are filled exactly once. Because exact fill rules are
45 not specified, reference rasterizer uses all valid combinations of
46 LEFT, RIGHT, TOP and BOTTOM.
48 Value interpolation is tested for lines and triangles with
49 vertex-specific colors, small deviation in interpolated color is allowed.
51 Multisample rasterization is tested with points, lines and triangles.
52 Because sampling pattern is unknown, deviation in produced colors is
