    EXA/mixed: ModifyPixmapHeader pitch fixes. (bug #33929)
    
    If there's a GPU copy and a non-zero devKind was passed in, set the GPU copy
    pitch to that instead of to a possibly bogus value derived from the new width.
    This is e.g. used by the radeon driver's drmmode_xf86crtc_resize hook, fixes
    https://bugs.freedesktop.org/show_bug.cgi?id=33929 .
    
    On the other hand, the system memory copy doesn't need the pitch to be aligned
    beyond the PixmapBytePad of the width.
