 devices.  Currently supported output targets include the X Window System (via
 both Xlib and XCB), Quartz, Win32, image buffers, PostScript, PDF, and SVG file
-output.  Experimental backends include OpenGL, BeOS, OS/2, and DirectFB.
-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.).")
