I changed the code to use freetype for drawing and also added the
config file which I speak about above. Currently only for labels.

static void popup_connect_window(void)
{
  struct te_screen *screen;
  struct te_screen_env env;

  screen = te_get_screen(root_window, "connect", &env);
}

and the following data file you get a picture like
http://freeciv.org/~rfalke/fs3_pics/screen-0004.png (and yes the log
window has the wrong colors).

---- start data/themes/default/connect.screen ----
[screen]
background="telescope.png"

[label_1]
x = 300
y = 100
width = 265
height = 220
align="nc"

text=_("anti-alias")
text-color="#ff0000"
text-size=35
text-font="verdana.ttf"
text-antialias=1

tooltip-color="#000000"
tooltip-background="#f4ed8b"
tooltip-size=12
tooltip-font="verdana.ttf"

[label_2]
x = 300
y = 150
width = 265
height = 220

text=_("no anti-alias")
text-color="#ff0000"
