In section 5.5.3, the handbook explains how to improve the quality of fonts on
LCD monitors by enabling subpixel smoothing. However, the section does not
draw attention to the fact that the print/freetype2 port must be compiled with
non-default options to allow this.
The following patch adds a brief explanation. I am unsure whether the port
makefile's patent warning should be mentioned.

<para>One last point: with an LCD screen, sub-pixel sampling may be
