    qrgb565: Use the trivial qt_memconvert() and qt_rectconvert()

    Use memcpy() instead of the generic conversion routines where both template
    arguments are qrgb565. Yields a massive performance gain for tiling opaque
    (background) images in WebKit on 16-bit displays.

    This was previously restricted to Q_WS_QWS for some unknown reason.
