Bug #4686: Fix a minor GeForceFX + flatpanel + video overlay corruption issue.
    
    This change was originally in XFree86 CVS, nv_dac.c version 1.36 but got
    reverted accidentally.

G80: Add an LVDS flat panel scaling property.
    
    This property controls how non-native resolutions are scaled to the native
    resolution.  Valid values are:
        * center: 1:1 pixel ratio with black borders to center the image.
        * fill: Scale image to the native resolution.
        * aspect: Scale image to fit the screen, adding black bars to preserve
          square pixels.
    Defaults to "aspect".  Change with "xrandr --output LVDS --set scale <foo>".
