     Selects the amount to scale the display on the first pass.  There is an Auto preset as well as presets for fixed 1x, 2x1, 2x, 3x, and 4x ratios.  In addition, a ratio can manually be set anywhere from 0.25x0.25 to 16x16.  The Auto preset will automatically double pixels horizontally if the horizontal resolution is 400 pixels or less, and will double pixels vertically if the vertical resolution is 300 or less.

     Selects the filter to use for scaling the output when the resolution is different than the desktop resolution, or when the optional 1st pass scaling is in effect, the scaled resolution is different from the desktop resolution, 
     as well as for blitting operations.  The following methods are available:
