-Cairo is designed to produce consistent output on all output media while
-taking advantage of display hardware acceleration when available
-eg. through the X Render Extension).
-
-The cairo API provides operations similar to the drawing operators of
-PostScript and PDF.  Operations in cairo including stroking and filling cubic
-Bézier splines, transforming and compositing translucent images, and
-antialiased text rendering.  All drawing operations can be transformed by any
-affine transformation (scale, rotation, shear, etc.).")
