Vertically centering text. The text height in fit_textline( ) is the capheight, i.e. the
height of the capital letter H, by default. If the text is positioned in the center of a box it
will be vertically centered according to its capheight (see Figure 8.6a).
To specify another height for the text box we can use the Matchbox feature (see also
Section 8.4, »Matchboxes«, page 243). The matchbox option of fit_textline( ) define the
height of a Textline which is the capheight of the given font size, by default. The height
of the matchbox is calculated according to its boxheight suboption. The boxheight suboption
determines the extent of the text above and below the baseline.
matchbox={boxheight={capheight none}} is the default setting, i.e. the top border of the
matchbox will touch the capheight above the baseline, and the bottom border of the
matchbox will not extend below the baseline.
