Current SVN can handle non-square pixels. However, you must specify a
DisplaySize such that the calculated aspect ratio is that of your
physical display (i.e. if you have a 16:9 TV, make sure the DisplaySize
you provide has a 16:9 ratio). Any DPI (even different DPI's on the X
and Y axes) works.
If you're using NVIDIA display drivers, be very careful--as they will
ignore DisplaySize and DPI by default.
