The origin for a line is always implied to be the top-left corner of it bounding rectangle. When the bounding rectangle's height is non-zero, the slope of the line is negative (resembles a backslash); to make the slope positive, set the InvertY property to true.
To render a horizontal line, set the Height component of the Size property to zero.
To render a vertical line, set the Width component of the Size property to zero.
