It can be used as the context plus driver of the GDI, GDK and X-Win based +drivers. But its primary focus is the GDK base driver.

The main motivation for the use of Cairo was transparency for all the primitives. Beyond that we got other features like anti-aliasing, gradient filling, transformations and other back-ends (support to rendering: PDF, PS, SVG and IMAGERGB surfaces).

This driver still does not completely replace the X-Windows, GDK and GDI Windows base drivers, because Cairo does not have support for bitwise XOR operations and for complex clipping regions.

Using Cairo it is allowed to create more that one canvas at the same time for the same Window. And they can co-exist with a standard GDK, Win32 or X-Windows canvas.

To enable the use of Cairo based drivers you must call the initialization function - cdInitContextPlus() once and link to the libraries "cdcairo" and "cairo".
