I don't know the exact figure for rptation, but I cheated. I copied the template to a larger new image, rotated it to be paralell with the sides of the new image, textured it and then copied it back onto the original template. You have to be very careful on this stage, but it does make it lots easier to texture.

The greatest part of wisdom is learning to develop  the ineffable genius of extracting the "neither here nor there" out of any situation...."
