This enables Vertex Rounding Hack and has a game patch for two bugs
resulting from game choices. The game draws an efb copy at
coordinate 0.00195313 to 1.00195 repeating which only works due to how the
numbers work out at low resolution.
The Vertex Rounding Hack is a null operation on 1x IR, so there should
be no concern enabling it by default since higher resolutions are
completely broken without it.
