Issue description
In Synfig Studio the interface response time is slow. It makes difficult for the user to quickly see the results of the changes made on the animation leading into slow workflow. One of the reasons of the slow response is the amount of time that the floating point calculations take for the SOFTWARE render.

The render speed can be improved by using Cairo libraries instead of the Software renderer. Alternatively (and ideally) Open GL would be the other solution but Cairo graphics has been selected since it has also the ability to use GPU load via cairo_gl to increase render speed.

Finally, the Cairo port is completed. There are some minor remaining issues related to blending methods and color rendering, not fully accurate in some cases. From this point, the further work for Cairo port should be bug fixes and performance improvements where applicable.
