[Open-graphics] Please help: Video controller: Synthesis warnings that should be fixed

[Timothy Normand Miller]

These may be nothing, but they should be investigated:

    Related source file is "../../../vid_ctl/pixel_send.v".
WARNING:Xst:1780 - Signal <pv_del2> is never used or assigned.
WARNING:Xst:646 - Signal <send_reload> is assigned but never used.
WARNING:Xst:646 - Signal <deq_divider<5>> is assigned but never used.

That <ret> one makes me nervous. I haven't looked at it, but we need
to make sure that the RET instruction isn't broken.
