31e5c31af7Sopenharmony_ciDescription:
32e5c31af7Sopenharmony_ci
33e5c31af7Sopenharmony_ciTexture format tests render a single quad, consisting of two triangles.
34e5c31af7Sopenharmony_ciThe viewport is configured to match the texture size. Texture coordinates
35e5c31af7Sopenharmony_ciyield a 1:1 mapping from texels to framebuffer pixels. Thus filtering
36e5c31af7Sopenharmony_cishouldn't affect the final rendered image.
37e5c31af7Sopenharmony_ci
38e5c31af7Sopenharmony_ciThe rendered image is compared against a reference that is produced by
39e5c31af7Sopenharmony_cireference renderer. A simple threshold-based comparison is used.
