Auto mode notes.

    As of 01/24/13 and version of DMDX it is no longer absolutely necessary to use TimeDX to time video modes and otherwise inspect your machine's ability to run DMDX.  Instead DMDX's Auto mode can be used.  The DMDX installer no longer drops "pure" shortcuts to DMDX and TimeDX on the desktop but instead drops a shortcut that runs DMDX with the -auto parameter that instructs it not to throw an error if a setting that would normally be setup by TimeDX is found, but to instead either take the default action or in the case of a video mode request take a good guess at what the likely timing parameters will be.  In the past this wasn't possible, these days it appears that the reliability of Windows drivers is high enough that we can forgo the rigmarole of using TimeDX.  I still recommend using TimeDX to ascertain the machine's ability to run DMDX however having to time each and every video mode used was getting old when DMDX's guesses made based on what more modern operating systems tell it have been performing perfectly well.

    There are a few minor caveats (beyond the general hands off nature of letting one's software make all the decisions itself) in that auto mode will issue a warning if you specify the duration of a display in ticks (retrace intervals), after that it shuts up.  Initially developed for remote testing where no experimenter setup of a machine was possible and indeed one had no idea what was available the assumption was that you use millisecond times to specify frame durations because you had no idea how long a tic is.

    In addition the default video mode is no longer the ancient 640x480 8 bits per pixel video more prevalent when DMDX was being developed, DMDX peeks at what the desktop is using and uses that instead.  Basically <VideoMode>, long an essential staple of item file use is optional with Auto mode.
