* vidputs(newmode, outc)
*
* newmode is taken to be the logical 'or' of the symbols in curses.h
* representing graphic renditions. The teminal is set to be in all of
* the given modes, if possible.
*
* if set-attributes exists
* use it to set exactly what you want
* else
* if exit-attribute-mode exists
* turn off everything
* else
* turn off those which can be turned off and aren't in
* newmode.
* turn on each mode which should be on and isn't, one by one
*
* NOTE that this algorithm won't achieve the desired mix of attributes
* in some cases, but those are probably just those cases in which it is
* actually impossible, anyway, so...
