EgaTxtFontRec

 One field of the EgaSavePtrRec points to an EgaTxtFontRec.  Initially,
 this structure does not exist, but it may be installed by DOS national
 language support or other TSR code.

                           containing bLenOneChar bytes (usually 8 or 14).
                           See INT 1FH for related info.

 On VGA systems, a second 256-character font may be setup by initializing
 the EgaSavePtrRec.pfSavePtr2 to a VgaSavePtr2Rec and setting its
 pfTxtAuxFont field to point to another EgaTxtFontRec structure.  This
 secondary character set would be activated according to the mode values
 in the abModes field.
