This GTK2 package has been whittled down for the Tiles@Home project, providing the minimum needed to allow Inkscape to be driven by the T@H client scripts.

This fast and versatile library is used all over the world for all libgnome (GNOME) applications, gimp (The GIMP), and several others. Originally, version 1 was written for the GIMP and hence has the name GIMP ToolKit. Many people like it because it is small, efficient, and very configurable.

Most applications which used gtk (GTK1) have since switched to GTK2. Besides a more flexible API, it provides improved text rendering using pango (Pango) and many other goodies, but GTK+ 2 lacks compatibility with GTK1, so to switch, programmers have to port applications to it.

To develop applications with gtk, you need the package gtk2-devel.
