render/picture.c Initialize the format of a source picture to

    PICT_a8r8g8b8. Fixes a failure in the gradients test of rendercheck. In
    the long term we could do better by setting the format to something
    without alpha whenever the gradient doesn't contain colors with alpha.
    This triggers a reduction of the over operation to a pure source
    operation.
