The automatic code causes OSD::ReInit to be called() because the actual
video size has changed (4:3 vs 16:9).  The manual stuff is just changing
the display scaling though which isn't as simple as just calling OSD::ReInit,
some calculations are going to have to be made and maybe some OSD changes
in order to get the OSD to realize that even though the video is say
640x480, that it can only use 480x360 in the middle of that because of
the hardware scaling (when in 4:3 zoom mode).
