DoubleX - a small patch to force mode promotion on all NTSC and PAL
	  screens on AA-equipped computers.

Mode promotion on the A4000 will take a request from a program to open
a screen, and either scandouble or de-interlace that screen.  However,
if the program specifically asks for an NTSC or PAL screen mode, then 
the OS feels compelled to give the program what it asked for - even if
that means a flickering screen, or a 200 line display.

DoubleX does what Mode Promotion does, but it does it for all
OpenScreenTagList() requests.  Programs that the standard Mode Promotion
will not promote, such as DPaint or ADPro, will be promoted by DoubleX.

To install DoubleX, copy it to some directory such as "Sys:Tools", and
add a line like this to your "S:User-Startup" file:
	
	"Run >NIL: <NIL: Sys:Tools/DoubleX"

You cannot drop DoubleX into the WBStartup drawer - it will not run
from Workbench.  It will quit if you send it a Ctrl-C break signal.
Warning: It does not check to make sure that nothing else has patched
the OpenScreenTagList() vector when it exits, and if something else
has, then your system may be left in an unstable state.  Quitting 
DoubleX is not generally a good idea.
