    gloverlay: Fix upside down and miss-aligned JPEG

    LibJPEG uses macroblock of 8x8 sample. In this element we use RGB and
    Y444, two 24bit formats that are stored in 32bit pixels. This mean we
    have 32x32 bytes macroblocks. For this reason, we need to allocate
    our buffer slightly larger. We also need to pass the line pointer in
    the right order, otherwise the image endup upside-down.

Take note that in case of libjpeg error, the element abort the process. I think
this is why jpegdec is using long jump.
