Once again, I've rendered old themes obselete. :-)
I added a new config file attribute and command-line parameter. The
option is --default-font-index, but I wouldn't necessarily use it.
The config file attribute makes more sense. :-)
Anyway, your themes will now need to have a line like this:
font default <index>
in the attributes section. This tells Eterm which font it should use
on startup. (<index> is a number between 0 and the highest-numbered
font you define.) You can now have up to 256 fonts. Font 0 is no
longer necessarily the default font; it is the smallest font. And the
larger the font index, the larger the font should be. (Of course,
this assumes you want Ctrl-> and Ctrl-< to increase/decrease your font
size. In reality, you can have your fonts in any order, and those
keys will cycle through them in order.)
Before, font 0 was always the default, and you didn't have much
freedom in rearranging your fonts. Plus, you were limited to 5. Not
any more. :-) The new system is much more straight-forward, logical,
and powerful.
So please be sure to update your themes by hand, or remove your theme
directory before installing this new version. If your theme lacks
the "font default" line, your Eterms will start with the wrong font.

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.

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.
