    tests: Avoid rounding error and correct source pixels
    
    In float-to-8bit.c and "float -> u8 6", change 0.3 to 0.301 since 0.3
    / 0.6 * 255 = 127.5, so the slightest platform specific rounding error
    will give different results for u8 (127 or 128).
    
    Also correct G'a and B'a values in the third pixel to match expected
    values, the source values seems to have forgotten about
    premultiplication.
