*------ Font Styles --------------------------------------------------
FS_NORMAL	EQU	0	; normal text (no style attributes set)
    BITDEF  FS,UNDERLINED,0	; underlined (under baseline)
    BITDEF  FS,BOLD,1		; bold face text (ORed w/ shifted right 1)
    BITDEF  FS,ITALIC,2		; italic (slanted 1:2 right)
    BITDEF  FS,EXTENDED,3	; extended face (must be designed)

    BITDEF  FS,COLORFONT,6	; this uses ColorTextFont structure
    BITDEF  FS,TAGGED,7		; the TextAttr is really an TTextAttr,

*------ Font Flags ---------------------------------------------------
    BITDEF  FP,ROMFONT,0	; font is in rom
    BITDEF  FP,DISKFONT,1	; font is from diskfont.library
    BITDEF  FP,REVPATH,2	; designed path is reversed (e.g. left)
    BITDEF  FP,TALLDOT,3	; designed for hires non-interlaced
    BITDEF  FP,WIDEDOT,4	; designed for lores interlaced
    BITDEF  FP,PROPORTIONAL,5	; character sizes vary from tf_XSize
    BITDEF  FP,DESIGNED,6	; size is "designed", not constructed
*				; note: if you do not set this bit in your
*				; textattr, then a font may be constructed
*				; for you by scaling an existing rom or disk
*				; font (under V36 and above).
    ;-- bit 7 is always clear for fonts on the graphics font list
    BITDEF  FP,REMOVED,7	; the font has been removed
