Most of the conformance tests read a pixel value and assert that it matches a known value. However they were all doing this with slightly different methods. This adds a common test_utils_check_pixel function which they now all use. The function takes an x and y coordinate and a 32-bit value representing the color. It is assumed that writing a known color is most convenient as an 8 digit hex sequence which this function allows. There is also a test_utils_check_pixel_rgb function wrapper which takes the components as separate arguments. This is more convenient when the expected color is also calculated by the test.
