allocated type.
The main reason for this is to stop it from taking up a fixed large
amount of space in every 'struct value' subunion in conf.c, although
that makes little difference so far because Filename is still doing
the same thing (and is therefore next on my list). However, the
removal of its arbitrary length limit is not to be sneezed at.

by introducing a wrapper around an individual unifont which falls back
to Pango (which already has built-in fallback) in the case where the
selected font doesn't support the glyph in question.
The wrapper itself is a (vestigial) subclass of unifont, to minimise
disturbance at the call sites.

converted by the client into the appropriate MBCS/SBCS.
This also means I can remove 'real_charset' from the public-facing
contents of the unifont structure.

data channels. Should comprehensively fix 'half-closed', in principle,
though it's a big and complicated change and so there's a good chance
I've made at least one mistake somewhere.
All connections should now be rigorous about propagating end-of-file
(or end-of-data-stream, or socket shutdown, or whatever) independently
in both directions, except in frontends with no mechanism for sending
explicit EOF (e.g. interactive terminal windows) or backends which are
basically always used for interactive sessions so it's unlikely that
an application would be depending on independent EOF (telnet, rlogin).
EOF should now never accidentally be sent while there's still buffered
data to go out before it. (May help fix 'portfwd-corrupt', and also I
noticed recently that the ssh main session channel can accidentally
have MSG_EOF sent before the output bufchain is clear, leading to
embarrassment when it subsequently does send the output).

'Config' in putty.h, which stores all PuTTY's settings and includes an
arbitrary length limit on every single one of those settings which is
stored in string form. In place of it is 'Conf', an opaque data type
everywhere outside the new file conf.c, which stores a list of (key,
value) pairs in which every key contains an integer identifying a
configuration setting, and for some of those integers the key also
contains extra parts (so that, for instance, CONF_environmt is a
string-to-string mapping). Everywhere that a Config was previously
used, a Conf is now; everywhere there was a Config structure copy,
conf_copy() is called; every lookup, adjustment, load and save
operation on a Config has been rewritten; and there's a mechanism for
serialising a Conf into a binary blob and back for use with Duplicate
Session.
User-visible effects of this change _should_ be minimal, though I
don't doubt I've introduced one or two bugs here and there which will
eventually be found. The _intended_ visible effects of this change are
that all arbitrary limits on configuration strings and lists (e.g.
limit on number of port forwardings) should now disappear; that list
boxes in the configuration will now be displayed in a sorted order
rather than the arbitrary order in which they were added to the list
(since the underlying data structure is now a sorted tree234 rather
than an ad-hoc comma-separated string); and one more specific change,
which is that local and dynamic port forwardings on the same port
number are now mutually exclusive in the configuration (putting 'D' in
the key rather than the value was a mistake in the first place).
One other reorganisation as a result of this is that I've moved all
the dialog.c standard handlers (dlg_stdeditbox_handler and friends)
out into config.c, because I can't really justify calling them generic
any more. When they took a pointer to an arbitrary structure type and
the offset of a field within that structure, they were independent of
whether that structure was a Config or something completely different,
but now they really do expect to talk to a Conf, which can _only_ be
used for PuTTY configuration, so I've renamed them all things like
conf_editbox_handler and moved them out of the nominally independent
dialog-box management module into the PuTTY-specific config.c.

This was intended for code cleanliness, but a side effect is to make

accidentally ignored, and nobody seems to have noticed before!

'string' field in a GdkEventKey structure as ISO-8859-1, which was
correct for GTK 1.2 but in 2.0 that field is encoded according to
the current C library locale. Hence, we now process that field by
converting it to UTF-8 via trips through both libc and libcharset,
and then let lpage_send() convert from UTF-8 back to whatever it's
supposed to actually go down the line in.

with the switch to GTK2. This turns out to be because, where GTK1
represented the scroll wheel as mouse buttons 4 and 5 and generated
GdkEventButton when it was moved, GTK2 has moved wheel actions out
into a new event type GdkEventScroll which we were not handling. Now
we do, so scroll wheel support should be back in place.

client- and server-side fonts into a single namespace was mainly to
hope there would naturally be no collisions, and to provide
disambiguating "client:" and "server:" prefixes for manual use in
emergencies.
Jacob points out, however, that his system not only has a namespace
clash but worse still the clash is at the name "fixed", which is our
default font! So, modify my namespace policy to use the
disambiguating prefixes everywhere by default, and use _unprefixed_
names only if the user types one in by hand.
In particular, I've changed the keys used to store font names in
Unix saved session files. Font names read from the new keys will be
passed straight to the new unifont framework; font names read from
the old keys will have "server:" prepended. So any existing
configuration file for GTK1 PuTTY should now work reliably in GTK2
PuTTY and select the same font, even if that font is one on which
your system (rather, your client+server combination) has a font
namespace clash.

gtk_container_dequeue_resize_handler in request_resize() was;
everything seems to work fine without it. So I'm removing the
nonportable GTK 2 instance of it, and if anything ever goes wrong as
a result then I'll at least find out what the problem was.

explicitly deals with GdkFont out into a new module, behind a
polymorphic interface (done by ad-hoc explicit vtable management in
C). This should allow me to drop in a Pango font handling module in
parallel with the existing one, meaning that GTK2 PuTTY will be able
to seamlessly switch between X11 server-side fonts and Pango client-
side ones as the user chooses, or even use a mixture of the two
(e.g. an X11 font for narrow characters and a Pango one for wide
characters, or vice versa).
In the process, incidentally, I got to the bottom of the `weird bug'
mentioned in the old do_text_internal(). It's not a bug in
gdk_draw_text_wc() as I had thought: it's simply that GdkWChar is a
32-bit type rather than a 16-bit one, so no wonder you have to
specify twice the length to find all the characters in the string!
However, there _is_ a bug in GTK2's gdk_draw_text_wc(), which causes
it to strip off everything above the low byte of each GdkWChar,
sigh. Solution to both problems is to use an array of the underlying
Xlib type XChar2b instead, and pass it to gdk_draw_text() cast to
gchar *. Grotty, but it works. (And it'll become significantly less
grotty if and when we have to stop using the GDK font handling
wrappers in favour of going direct to Xlib.)

represent a launchable session, unless the user can be construed to
have really meant it. This means:
- starting up PuTTY when the Default Settings are launchable still
brings up the config box, and you have to hit Open to actually
launch that session
- double-clicking on Default Settings from the config box will load
them but not launch them.
On the other hand:
- explicitly loading the Default Settings on the command line using
`-load' _does_ still launch them.

I hesitate to say `fixes', but ... this change _causes to go away_
the weird problem I had with blank host key dialogs. I have no
understanding of the chain of cause and effect between gdk_input_add
with zero flags and missing redraw events, but it seems like a
change I should make anyway, so I'm going to do so and hope the
problem doesn't come back :-/

under X: instead of having two separate fixed-width fonts one of
which is twice the width of the other, you can instead have a single
font in which some characters are twice as wide as others.
This is implemented very simply: if you specify a wide font, it will
be used for wide characters, and if you don't then the normal font
will be used for wide characters (so they'd better _be_ wide in that
font, or there'll be trouble).
I got this idea from Jed, whose latest version supports UTF-8 and
requires a font of this type. If there are going to be X fonts like
that kicking around, there will doubtless be people who want to use
them.
