- *------ 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

-
- *------ 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
