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.
