MattsterMaster,

TKGB accidentally put this after Vista Hair Texture, when it should have been before it. I better PM him about that.
Anyways, you can also make a 4x4 square and zoom to 25% or a 2x2 square and zoom to 50%. If making the square is harder, make the smallest one you can; if shift dragging is harder, always make an 8x8.
