OK.

No, this means that the configuration macros
`FT_CONFIG_OPTION_USE_LZW' and `FT_CONFIG_OPTION_USE_ZLIB' (in file
`ftoption.h') should be defined, and that the line

  FONT_MODULES += pcf

in file `modules.cfg' is present.

The description is in file `freetype2-demos/README'.  If you follow
this to the letter, everything should work.  Note that it's probably
easiest if you compile FreeType (the library, not the demo programs)
with

  make devel && make

for compiling the demo programs instead of calling the configure
script.

Well, inspecting glyphs usually needs something to look at, right?
But no, not all demo programs need a GUI.

No.  FreeType provides a uniform interface to all fonts.  If you want
something simpler, look at the FreeType tutorial examples.
