Ok, now that I look at this I'm not sure I understood. That function
accepts "pre-opened FreeType face" - what does it mean? I thought I
could somehow pass a path to a file font, do I need to first somehow
open the font via FreeType and then it can be used in Cairo? Perhaps
are there some examples somewhere?

 cairo_show_glyphs() accepts cairo_glyph_t which has this "x offset".
However, the docs say: "Note that the offsets given by x and y are not
cumulative". Does it mean the positions of glyphs of my text are to be
positioned absolutelly, i.e. I have to compute every position, like
"previous_glyhp_position + this_glyph_advance_x +
this_glyph_my_offset_x"?
