Provides anti-aliased vector-based rendering for X. Paths consist of line segments and cubic splines and can be rende
red at any width with various join and cap styles. All colors may be specified with optional translucence (opacity/alpha) and c
ombined using the extended Porter/Duff compositing algebra as found in the X Render Extension.

Cairo exports a stateful rendering API similar in spirit to the path construction, text, and painting operators of PostScript,
(with the significant addition of translucence in the imaging model). When complete, the API is intended to support the complet
e imaging model of PDF 1.4.
