video/bfm_dm01.cpp: Convert back to using outputs and update layouts.

Browse Source 
Outputs no longer require string formatting and hash lookups, and only
changes to output values result in notifications.  Performance is
better than before.  We never had any kind of post-processing to make
the "alternate pixels" screen bitmap look like a DMD, and the bilinear
scaling looked awful.
