both horizontal and vertical?

(I posted this to gtk-app-devel-list at gnome.org on 2006-08-08 but didn't get an answer)
I am drawing text on a Cairo context with the help of Pang Cairo.
If I use a font with 72 points then an M should be aproximately one
inch tall (I guess, maybe I am wrong), for this, I get the resolution of
my monitor and I tell that to Pango, so I got my expected result.
Luckily my monitor has square pixels, so I have 81 dpi both
horizontally and vertically.
But now I wonder: ¿what happens on a non square pixel monitor or on
My guess is that the fonts would look distorted because the diferent
resolutions aren't taken into account by Pango.
I looked in the documentation and header files and I didn't found a
function to specify the resolution separately for vertical and horizontal.
I am a bit lost now, so I appreciate if someone can iluminate my
route to salvation :) .
Thanks for sharing your knowledge!
P.s.: GNOME seems to be using 96 DPI by default although my monitor
correctly reports 81 dpi to X _and_ to GTK, so actually my fonts aren't
the size they should be in the real physical world, but I will not bug
about this until I get more knowledge about fonts, etc..., also, it
doesn't have the possibility to specify diferent resolutions for
horizontal and vertical... I wonder how fonts would look in a non square
pixel monitor though I think those monitors are hard to find today...
