Okay, there are a few changes here. First off, I made multi-byte font
support the default now, as long as you have ISO 10646 fonts. In
order to do this, I made the default encoding type "Latin1" so as not
to interfere with 8-bit ISO 8859-1 characters. This means that if you
relied on the default multi-byte encoding method to be SJIS, you'll
need to update your theme files.
I also set it up so that Eterm will ignore SIGHUP, at least until I do
something with it (like reloading the theme or something).
I fixed the proportional font size algorithm. If there is more than
a 3-pixel variance between the minimum and maximum sizes for glyphs in
a proportional font, Eterm will set the size to 2 standard deviations
above the average width. This is so that they won't look so spread
out and ugly, but it still doesn't look perfect. Not much I can do on
that front...terminals must have fixed-width columns.
And then there's the biggie. I put in the ability to configure the
now-infamous font effects. I left a black drop shadow in as the
default, but you can now customize it via the --font-fx option or in
the config file using "font effects <stuff>" in the attributes
context. You can even use "fx" instead of "effects" for short.
So what goes in the <stuff> part? Well, you have several options.
To use a single-color outline, say "outline <color>". Likewise, a
single-color drop shadow is "shadow [corner] <color>"; "bottom_right"
is the default corner if you don't specify one. For a 3-D embossed
look, "emboss <dark_color> <light_color>". The opposite, a carved-
out look, can be had with "carved <dark_color> <light_color>". (Of
course, with those last two, the 3-D look will only work if you
choose the colors wisely.)
Those are all the shortcuts. The long way is to specify a series of
corner/color pairs, like "tl blue" for top-left blue, or
"bottom_right green". You can abbreviate using "tl," "tr," "bl," or
"br," or you can spell out "top_left," "top_right," "bottom_left," or
"bottom_right." If you omit a corner name, the first one defaults to
top-left, the second to top-right, and so on as listed above.

Lots of changes here. First off, this should fix the background draw
bug with transparency that several people pointed out. While I was
at it, I also cleaned up a lot of other related stuff. Three-state
images should be a lot more robust now.
Then again, some stuff may be broken entirely from this, so let me
know. :-)
For one thing, the various image modes should work as expected now.
You can allow and disallow modes for the various widgets. The
fallback mode is "solid" now, rather than "image," so you can cause
a certain widget to refuse to use an image if you want to. If you
specify an image without specifying a "mode" line that allows the
"image" mode, your image will not appear. <-- READ THIS TWICE! I
had to go back and fix all the theme files because of this, so you
will need to remove your current theme directory and allow Eterm's
"make install" to put the new ones in place; otherwise, everything
will go back to being solid colors. =]
Anytime something changes this drastically, there are bound to be
problems. Let me know if you find any of them. :)

This is the first public availability of the work thus far on Eterm
0.9.1. There's quite a bit of new stuff here.
* Added scrollbar thumb support.
* Completely redid the terminfo/termcap stuff. The terminfo file is
now compiled (by tic) and installed by default (unless you specify
--without-terminfo). The config files still say xterm, though,
because some programs (like SLang and GNU mc) use the silly algorithm
of "Is $TERM set to xterm?" to detect mouse reporting support in a
terminal. =P But if you don't ever use xterm, you can use Eterm's
termcap and just name it "xterm" instead. Thanks to Marius Gedminas
<mgedmin@takas.lt> for his patch that started this whole revamp.
* Added the kEsetroot script for KDE users from Dax Games
<dgames@isoc.net>.
* You can now configure the Home and End emulation via --with-home=
and --with-end= options to configure. The --with-terminfo option is
also new, and --enable-xim is now the default.
* Added a new image state, disabled, for when Eterm loses focus. This
is supported by all widgets (well, all those that could possibly be
on screen when Eterm lost focus), even the background image. So you
could actually have all your images darken on focus out and restore
to normal on focus in.
* Widget colors formerly dealt with as colors (menu text color,
scrollbar color, etc.) are now handled by the imageclasses. Each
image state can have a foreground and background color defined. The
current exception is the background image; I hope to add that later.
The foreground is the text color and the background is the object
color (for solid color mode). So menu text color is set by the menu
imageclass. And again, for unfocused colors, use the disabled state
of the imageclass.
* Proportionally-spaced fonts are now handled much better. They are
still forced into evenly-spaced columns (it's a terminal for crying
out loud!) but at least you don't end up with Eterm's wider than your
screen. :-)
* Home on refresh is gone, as is home on echo. It's now much simpler.
There are two options: home on output, and home on input, the former
being a combination of echo and refresh. Also, keypresses that don't
necessarily have corresonding output can trigger a home on input,
like Ctrl-End or whatever...ones that don't have special meaning.
Credit to Darren Stuart Embry <dse@louisville.edu> for pointing out
this issue and the one with "m-" in font names.
* I finally got around to re-merging the new parser stuff from my
work on the Not Game. Closed up some old potential behavior quirks
with theme parsing.
* Added a new escape sequence to fork-and-exec a program. Also added
a scrollback search capability to highlight all occurances of a string
in your scrollback buffer. Use the new "Etsearch" utility to access
it. "Etsearch string" to search for a string, then "Etsearch" by
itself to reset the highlighting.
* And of course, the biggie. Eterm now supports a completely-
customizeable buttonbar. Not a menubar, a buttonbar. It can have an
arbitrary number of buttons, and each button can perform an action,
just like a menuitem. So a button could bring up a menu (like a
menubar) or launch a program (like a launchbar) or perform an
operation (like a toolbar). Each button can have an icon, text, or
both. And you can have buttons left- or right-justified in the
buttonbar. You will eventually be able to have an arbitrary number
of buttonbars, but I'm still working on that.
As with any change this big, things could very easily be broken. So
beware. :-) I have tested this myself, and everything seems to work,
but I can't test every possibility. Let me know if you find anything
that's broken, and enjoy!
