[cairo] is unaligned text possible?

[David Vanderson]

Hello,

I'm trying to render text not aligned to pixel boundaries:

cairo_move_to (cr, 100.3, 100.3);
cairo_show_text (cr, "hello");

It seems that regardless of the font options I set, the baseline (for 
instance) is always snapped to a whole pixel. I'm sorry if this is a 
known issue, but is this intentional?

Thanks,
Dave
