X-term

double-high/double-wide characters

I have implemented double size characters in stages:
    - Like Kermit, XFree86 xterm can show normal characters spaced at the proper intervals.
    - If your font server cooperates (e.g., X11R6), you can display many fixed fonts in double-size, though not all.
    - XFree86 xterm can also generate its own line-drawing characters, which normally are missing from fixed fonts except for those that were designed for xterm.
- Other than the limitations which the font server may impose, the double size characters are drawn properly.

printer interface

Done, except for the corresponding support in the VT52 emulation. It would be nice to have a dialog to control this.

allow alternate libraries for popup-menus and dialogs

My configure script currently provides tests for the variations of
Athena widgets (Xaw3D, neXtaw). I intend to make additional changes to
support Motif scrollbars and menus. Motif requires a different style of
interface for the menus: binding a popup menu to control right mouse may
cause the server to hang. As an intermediate step, I implemented a
toolbar for the Athena widgets. In turn, that works well enough except
with XFree86 4.x: the Xaw library geometry management is broken. (Other
implementations of the Athena widgets work well enough).

blinking text.

Just for completeness (though no one seems to want this feature).
