Hello xorg-devel list
  I would like to request a feature addition.  When someone wishes
to use X on a home theater they have a very real problem with over
scan of the TV.  The TV will clip many pixels all the way around
the image.  This means that scroll bars are not visible on the TV
screen and menu bars are cut in half, if visible at all.

  It would be great if there was a setting to have a black, or a
designated color, border around the image from X.  This would foul
the TV and allow the user to see all of the screen.  Unfortunately
different brands of TV's have different ways of dealing with over
scan so the size of the border needs to be set by the user and not
preset to some specific value.

  The Microsoft windowing system has ways to deal with this problem
so they are the dominate system for home theaters.  But I
personally don't want to reduce the level of my operating system
for this feature.  I would be very appreciative of this as I'm sure
millions of other people would be.  Also I suspect it wouldn't be
that difficult.  I haven't delved into the code for X but it seems
to me to just be a linear transformation from r2 to r2, not that
big of a deal.  Or one could just add lines of black pixels on all
sides and the TV wouldn't know the difference, brute force
sometimes is the best way.

  I truly hope you consider adding this feature.  It would help me
out and many others as well.  It would also open a market for X
that currently is being ignored.  With the advent of high speed
internet sites such as www.hulu.com and www.joost.com television
and movies are coming into the home on demand.  I currently use X
to view these sights but to navigate them I use x11-vnc and my
laptop to see all of the screen.  Please help me out and millions
of others and implement this feature.

Thank you
Joseph Murphy

PS
  If this is already possible and I am just ignorant of how to
accomplish it please educate me.
