OK, I was wrong, this actually does work!!! Woohoo! But its such a
small increment I hardly noticed.  Changing all the 1's for 5's fixed
it.

I have now added an osd_draw function similar to what you get at
ff/rr, but to show zoom level.  Its only 1 or 2 lines of code in
osd.c/h.  Please let me know if you guys are insterested in this and
I'll start to learn how to create patch's.
