    cairo: accelerate R'G'B'A u8 -> cairo-ARGB32 conversion · 6d890333

    Accelerate the R'G'B'A u8 -> cairo-ARGB32 conversion by processing
    the entire RGBA tuple in parallel (or, on 32-bit machines, in two
    parts), instead of component-by-component, using wide integer
    arithmetic/logic.  This speeds the conversion up by ~25%.
