but should not be used by normal X11 clients. X11 clients access fonts
via either the new API's in libXft, or the legacy API's in libX11.
+libXfont supports a number of compression and font formats, and the
+configure script takes various options to enable or disable them:
+
+ -- Compression types:
+
+ gzip - always enabled, no option to disable, requires libz
+
+ bzip2 - disabled by default, enable via --with-bzip2, requires libbz2
+
+ -- Font formats:
+
+ builtins - copies of the "fixed" & "cursor" fonts required by the
+ X protocol are built into the library so the X server always
+ has the fonts it requires to start up. Accessed via the
+ special 'built-ins' entry in the X server font path.
+ Enabled by default, disable via --disable-builtins.
+
+ freetype - handles scalable font formats including OpenType, FreeType,
+ and PostScript formats. Requires FreeType2 library.
+ Can also be used to handle bdf & bitmap pcf font formats.
+ Enabled by default, disable via --disable-freetype.
+
+ bdf bitmap fonts - text file format for distributing fonts, described
+ in http://www.x.org/docs/BDF/bdf.pdf specification. Normally
+ not used by the X server at runtime, as the fonts distributed
+ by X.Org in bdf format are compiled with bdftopcf when
+ installing/packaging them.
+ Enabled by default, disable via --disable-bdfformat.
+
+ pcf bitmap fonts - standard bitmap font format since X11R5 in 1991,
+ used for all bitmap fonts installed from X.Org packages.
+ Compiled format is architecture independent.
+ As noted above, usually produced by bdftopcf.
+ Enabled by default, disable via --disable-pcfformat.
+
+ snf bitmap fonts - standard bitmap font format prior to X11R5 in 1991,
+ remains only for backwards compatibility. Unlike pcf, snf files
+ are architecture specific, and contain less font information
+ than pcf files. snf fonts are deprecated and support for them
+ may be removed in future libXfont releases.
+ Disabled by default, enable via --disable-snfformat.
+
+ -- Font services:
+
+ xfs font servers - allows retreiving fonts as a client of an xfs server.
+ Enabled by default, disable via --disable-fc (font client).
+
+ If enabled, you can also use the standard libxtrans flags to
+ configure which transports can be used to connect to xfs:
+ --enable-unix-transport Enable UNIX domain socket transport
+ --enable-tcp-transport Enable TCP socket transport (IPv4)
+ --enable-ipv6 Enable IPv6 support for tcp-transport
+ --enable-local-transport Enable os-specific local transport
+ (Change --enable to --disable to force disabling support.)
+ The default setting is to enable all of the transports the
+ configure script can find OS support for.
