[dev] [surf] patch: zoom text

[stanio]

Hi.

Let me

- share another trivial piece of code: changing webkit's text size, rather
  than zooming the whole content, incl. images, table/div sizes, which
  behaves bad on some pages.

- and ask a question: Does anybody know how to get the default font size
  from webkit? Currently it is hardcoded to 12. 
  
  Or put a #define in config.h to let the user choose the size per compiled
  instance? 


cheers,
