Hi Astron,

well easiest would be to wrap border drawing with

 aOutdev.SetAntialiasing( aOutdev.GetAntialiasing() & ~ANTIALIASING_ENABLE_B2DDRAW );

, which simply disables antialiased rendering.

Same as above, but yeah, if you have pixel-accurate coordinates, and
only vertical & horizontal lines, you shouldn't get _any_ grey
levels (modulo bugs).
