Drawing surface is inverted in both axes.
Drawing surface is inverted in the horizontal axis.
Drawing surface is not inverted in either axis.
Drawing surface is inverted in the vertical axis.
Text formatter clients usually invert the horizontal axis, or X-axis, of the drawing surface when performing right-to-left layout of text content.
In a less common case, a text formatter client may invert the vertical axis, or Y-axis, of the drawing surface to achieve the effect of having the coordinate origin at the bottom-left position of the screen. This is a useful technique when drawing certain types of graphs.
