A few of the squares (most of them, actually) of progs/tests/crossbar are not rendered correctly. Annoyingly, the square that is just GL_REPLACE of the 0.5 gray texture is one of the incorrectly rendered squares. It is slightly too dark. This may be an artifact of specifying the textures as RGB888 and the driver converting them to RGB565. Regardless, the (1.0 - 0.5) square is too light, and the ((0.5 + 0.5) * 0.5) and (0.25 + 0.25) * 1.0) squares are much too dark. The result in every square is supposed to be RGB = {0.5, 0.5, 0.5}.
