[cairo] Objections to changing most text tests to use the internal font?

[M Joonas Pihlaja]

Hey,

Does anyone have any objcetions to me shifting most of the text test 
cases to use the Twin font?

Until recently a lot of the text tests have been failing for me due to 
mismatches between whatever font which is called "Bitstream Vera" on 
my system and the system used to generate the ref images.  A few 
months ago the stars have aligned for me and now the majority of them 
pass suddenly, so presumably they're now failing with other Bitstream 
Veras.

Cheers,

Joonas
