% This is cut-and-paste from the submission.  
% Obviously it will need some work.
Xr provides a vector-based rendering API with output support for the X
Window System and local image buffers. PostScript and PDF file output is planned.
Xr is designed to produce identical output on all output media while
taking advantage of display hardware acceleration through the X Render
Extension.  

Xr provides a stateful user-level API with support for the PDF 1.4 imaging
model. Xr provides operations including stroking and filling B\'ezier cubic
splines, transforming and compositing translucent images, and antialiased
text rendering.  The PostScript drawing model has been adapted for use
within C applications.  Extensions needed to support much of the PDF 1.4
imaging operations have been included.  This integration of the familiar
PostScript operational model within the native application language
environment provides a simple and powerful new tool for graphics application
development.

Xr and Xc provide an antialiased vector-based rendering API for the X
Window System. Xr provides a stateful user-level API with support for
the PDF 1.4 imaging model. Xr provides operations including stroking
and filling Bezier cubic splines, transforming and compositing
translucent images, and antialiased text rendering.

Xc sits below Xr and provides an abstraction layer over the backend
rendering system. Xc allows the graphics operations to target X server
drawables or client-side image buffers. Xc takes advantage of the
RENDER extension if available and performs client-side emulation of
RENDER for legacy X server.
