Glossary ❘ 57XFSX Font Server.XftAn extension introduced in XFree86 for managing glyph images of vector fonts at client side. This allowsX applications to add special effects to the glyphs, such as anti-aliasing.XFree86A free X Window implementation for PC, although Mac is also supported. It is developed on top of thefree source code from the X consortium (X.org), along with hardware drivers and some extensions. Itused to be the only X Window implementation for FOSS on PC, until recent forks 1by efforts such asXouvert, freedesktop.org X server, Keith Packard’s kdrive, and X11R6.7, the latest one which is endorsedby X.org itself. (See also: X.org.)XIMX Input Method framework, introduced in X11R6 as part of its I18N. It makes complicated text inputprocesses, such as those for CJK, possible.XKBX Keyboard extension, introduced in X11R6 as part of its I18N. It provides a method to describe keyboardlayouts, to combine multiple layouts, and to switch between them.XOMX Output Method framework, introduced in X11R6 but fully implemented in X11R6.5.1 to provide complextext rendering. But its late arrival, when rendering engines like Pango have already matured, makes itsusefulness questionable.X.orgThe X consortium that maintains the X Window system. Normally, it maintains the X specification andprovides the framework implementation source code in free license. In early 2004, triggered by licensechange in XFree86, a group of developers forked XFree86 source and made it X11R6.7 release in thename of X.org.X ServerThe service that provides interface to graphical hardware and input devices in the X Window system. Itsclients are called X Clients. (See also: X Client.)X WindowA graphical environment initially developed by the Athena project at MIT with support from some vendors,and later maintained by the X consortium. X Window is the major graphical environment for most Unixvariants nowadays.1In software, a project fork or branch happens when a developer (or a group of them) takes code from a project and starts to developindependently of the rest. This schism can be caused because of different goals or personality clashes. Definition available atwww.wordiq.com/definition/Fork_(software)
