Fixed HAI

Fixed horizontal motion does not vary from character to character or
font to font. The HAI is explicitly defined by control functions.
A fixed HAI is selected by any of the following:
▪ Pitch Select Mode (DECPSM) reset, and Set Horizontal Pitch
(DECSHORP) with last valid Ps ≠ 0
Spacing Increment (SPI) with last valid Pn2 ≠ 0
▪
▪ Set Horizontal Spacing (SHS) using any valid Ps
