I doubt it, as Gtk+ is not used for any font metrics or image handling (except for tool bar images). But different versions of freetype2 and/or the image libraries might influence this.
With your font (-unknown-DejaVu Sans Mono-normal-normal-normal-*-12-*-*-*-m-0-iso10646-1, aka monospace-9) i get:
(38.57142857142857 . 14.466666666666667)
So the width is the same as what you get, but the height differs. Strange.
Does (image-size (create-image "splash.xpm") t) return (270 . 217) ?
Go to *scratch* and evaluate (assuming there is a character at pos 1):
(font-info (font-at 1))
It should return:
["-unknown-DejaVu Sans Mono-normal-normal-normal-*-12-*-*-*-m-0-iso10646-1" "DejaVu Sans Mono:pixelsize=12:foundry=unknown:weight=normal:slant=normal:width=normal:spacing=100:scalable=true" 12 15 0 0 0]
15 is the font height (i.e. 217 / 15 = 14.466666...). Do you have that?
