While we're doing that, actually use it in SyncTERM so the offline
scrollback retains fonts.

Also, fix an issue where the current mode would be updated with
the custom parameters when you changed them.

Finally, remove some unused variables.

People are used to thinking about the aspect ratio of displays and
used to not thinking at all about that of pixels.  Most of the modes
are simplt 4:3 modes and the text area is the entire window.  The
only oddball here is the Commodore 64 and 128 40-column modes.
Because they have a border around them that's wider on the sides than
the top/bottom, the display aspect ratio is actually narrower than
a normal NTSC screen (6:5).  It seems the PAL version actually has
square pixels, but nobody has asked for a PAL Commodore mode, and I
think that has a different colour palette too so I'm not doing it.

Just to frustrate DigitalMan a bit, the default custom aspect ratio
is now 4:3 (but can be configured).  At present, modifying the custom
mode while *in* the custom modes "works", which no sane person would
want when adjusting the aspect ratio.

Instead, just set bar to the end and let ulist() sort it out.  It
sucks, but it sucks less.

This uses the 720x400 with 9x16 character cell that always made
BBSs look so terrible.

I do, so you should too!

Sheesh.

Which required a new ciolib option of course.
Only usable in X11 mode at present, though it may land for SDL
this weekend.

Clamp coordinate translation max
Fill using native pattern, not scaled pattern
Add a bad, broken, and slow even/odd fill
Fix logging when RIP is enabled
Use the same ellipse algorithm for partial as full ellipses
Detect diagonal movement in ellipse drawing and don't make the edge fat
Only recurse once in the flood fill
Implement the v2 poly bezier command
Enable filled pie slices
Add RIP_POINT command (basically a scaled pixel using line width)

The option basically controls forced EGA mode and reported terminal.

Sometimes the comment wasn't redrawn.
Also, remove configurable mouse actions stuff, not implemented in
13 years, I suspect I'll never do it.

Also note the spectacularily poorly named WIN_REDRAW and WIN_NODRAW
flags.  WIN_REDRAW indicates that this *is* a redraw of the menu,
which indicates that you don't need to redraw the menu (because it's
already correct on screen).  Weird, but not insane... WIN_NODRAW on
the other hand indicates this is *not* a redraw, and that the window
is incorrect on screen and you therefore *must* redraw the menu.

That is to say:
WIN_REDRAW prevents the window from being redrawn
WIN_NODRAW forces the window to be redrawn

The jury is still out on some details...
1) If you press ESC while editing the comment, it currently cancels
   the edit.  Would people expect ESC to exit the program instead?
2) The format/colours of the displayed comment... right now it's
   using the UIFC background colours, and not draing a border or
   window.
3) Just how long should the comment field be, and how should it be
   edited.

This is used by some BBSs to enable encryption without needing to
integrate the BBS user base into their SSH server (and presumably
so they don't need to run multiple SSH servers).  All users log in
with the same username (ie: "bbs") and no password is requested or
required.

Once the BBS starts, it prompts for the BBS user name and password
as normal.

In SyncTERM, the user/password/syspass fields are redefined as
SSHuser/BBSuser/BBSpassword and they are moved around when you
change the connection type.  This means that if you change a listing
that has a syspass to SSH (no auth) and back, the syspass is lost.

I'm not sure if I plan to fix this or not.

There are too many options now to fit in an 80x25 screen, so group
all the log options into a separate sub-menu.

While we're here, notice that we're writing paths up to MAX_PATH
into an 80-character buffer and fix that.

Also, since I used my work computer, it changed all tabs to four spaces...
*sigh*

There are a number of conio changes in here too... too many to list.  Check
the diffs if you actually want to know what changed.

Fixes https://sourceforge.net/p/syncterm/tickets/10/ as well as various color
corruption issues in offline scrollback that date back to the sixel "stuff"

music can be configured.

Reported by DigitalMan.
Twice.

Remove xlat.
Rearrange Commdore fonts to match ASCII.
Clean up C64 emulation a lot...
Set the Commodore background to black in CTerm... it seems pretty much
all terminals do this.

It's not unlikely that any utilities using SDL will have new issues... you
may want to hold off on updates for a bit until this settles unless you
don't use SDL mode.

Fixed but I think DigitalMan reported where the count of entries isn't
updated after and add/delete until you change to the settings menu and back.

is Custom, and you modify the custom mode.

This uses global pointers to automatic variables... and other insane things.

Hopfully this doesn't break the Borland or Watcom (?!) builds.
