    Extract pixel value for all formats to avoid hitting fallbacks.
    
    On failing to extract the pixel value for an alpha-only solid we
    actually triggered a fallback. Since this path is commonly hitting
    whilst fading in images, for example cairo_paint_with_alpha(), the
    fallback was detected during the Moblin boot sequence where it was
    adding a second to the overall boot time.
    
    See
      fallback intel: Moblin startup is hitting a composite fallback, costing
                      a ton of performance

    Based on the initial patch by Arjan van de Van.
