#461 fast forward or reverse speed X display

[xconan]

It would be great if you could add the rate of fast
forward or reverse speed as an default constrasting
overlay (user color defineable/font with outline?)like
>>1X >>2X >>3.5X etc... or in 1X<< 2X<< 3X<<. That
would definitely help people determining what speed
setting they are fast forwarding or rewinding at. thanks.
