- * vidputs(newmode, outc)
- *
- * newmode is taken to be the logical 'or' of the symbols in curses.h
- * representing graphic renditions. The terminal is set to be in all of
- * the given modes, if possible.
- *
- * if the new attribute is normal
- * if exit-alt-char-set exists
- * emit it
- * emit exit-attribute-mode
- * else 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...
- *
- * NOTE that we cannot assume that there's no interaction between color
- * and other attribute resets. So each time we reset color (or other
- * attributes) we'll have to be prepared to restore the other.
