Sorry, in an earlier email i replied to you what would work in 0.84,
didn't realized you were talking about 0.82.

In 0.84 Pango knows the resolution of the screen and scales all fonts
accordingly. This means that by using, say 10, the font will always
look good in all hw.

In 0.82 didn't knew about the screen, so we were scaling all fonts by
using style.zoom().

Aleksey, do you have an idea about what can do activity authors that
wish to provide a single bundle that looks good both in 0.82 and 0.84?

Thanks,

Tomeu
