This package is the same code as x11/Xrender. The main differences are that its uses other freedesktop.org xlib code as dependencies and does not use USE_X11. (This means that it doesn't need complete XFree86 to build.) A problem is that regular x11/Xrender installs to the same place. This will overwrite parts of x11/Xrender's files. This needs to be fixed so the correct version of "Xrender" is used depending on the setup.
