/* This test framework allows limited testing of rendering results. Things are rendered, shown on
 * the framebuffer, read back from there and compared to expected colors.
 *
 * However, neither d3d nor opengl is guaranteed to be pixel exact, and thus the capability of this test
 * is rather limited. As a general guideline for adding tests, do not rely on corner pixels. Draw a big enough
 * area which shows specific behavior(like a quad on the whole screen), and try to get resulting colors with
 * all bits set or unset in all channels(like pure red, green, blue, white, black). Hopefully everything that
 * causes visible results in games can be tested in a way that does not depend on pixel exactness

     * set by the compiler, it was added manually after compilation. Note that the COISSUE
     * flag on a color(.xyz) operation is only allowed after an alpha operation. DirectX doesn't
     * have proper docs, but GL_ATI_fragment_shader explains the pairing of color and alpha ops
     * well enough.

     * The shader attempts to test the range [-1;1] against coissued cnd, which is a bit tricky.
     * The input from t0 is [0;1]. 0.5 is subtracted, then we have to multiply with 2. Since
     * constants are clamped to [-1;1], a 2.0 is constructed by adding c0.r(=1.0) to c0.r into r1.r,
     * then r1(2.0, 0.0, 0.0, 0.0) is passed to dp3(explained above).

    /* The input data was designed for D3DFMT_L6V5U5 and then transferred

     * 0.0 (0) and 1.0 (63) for L, the neutral point 0 as well as -1 and 1.
     * Some other intermediate values are tested too. The input value -15
     * (min + 1) is tested as well. Unlike what OpenGL 4.4 says in section
     * 2.3.4.1, this value does not represent -1.0. In the interest of re-
     * using the expected output data the 8 bit and 16 bit values in V8U8
     * and V16U16 match (post-normalization) the 5 bit input values. Thus
     * -1, 1 and -127 are not tested in V8U8.
     *
     * 8 bit specific values like -127 are tested in the Q channel of
     * D3DFMT_Q8W8V8U8. Here d3d seems to follow the rules from the GL
     * spec. AMD's r200 is broken though and returns a value < -1.0 for
     * -128. The difference between using -127 or -128 as the lowest
     * possible value gets lost in the slop of 1 though. */
