16.3 RENDER - A new rendering system for X11

XRENDER is an experimental step in building a newer and modern graphics rendering system that can keep up with the demands of visual appearance on current user interfaces.

The X Rendering Extension (Render) introduces digital image composition as the foundation of a new rendering model within the X Window System. Rendering geometric figures is accomplished by client-side tesselation into either triangles or trapezoids. Text is drawn by loading glyphs into the server and rendering sets of them.
