Add antialias option

The attached patch adds an -antialias option to pdftocairo to allow setting the cairo antialias option for used for fonts and drawing.

I changed the blending into the page color code to use a push/pop group based on:

https://cgit.freedesktop.org/cairo/commit/test/pdf2png.c?id=f74b11415a1f7682dd50c222baa8815ef93681dc

However this does not seem to make any difference to the output when using "-antialias subpixel".

Carlos found some issues with this patch when running the regression tests. I've pushed out a couple of patches that revert the push/pop group and rename and fix an issue with the internal setAntialias().
