Ok so you're right, the xfconf property /Xft/DPI is in dpi, but it
correctly sets the xsetting Xft/DPI to 1024*dpi:

corsac at scapa: xfconf-query -c xsettings -p /Xft/DPI
177
corsac at scapa: dump_xsettings |grep Xft/DPI
Xft/DPI 181248
corsac at scapa: xfconf-query -c xsettings -p /Xft/DPI -r
corsac at scapa: xfconf-query -c xsettings -p /Xft/DPI
Property "/Xft/DPI" does not exist on channel "xsettings".
corsac at scapa: dump_xsettings |grep Xft/DPI
Xft/DPI 179200

(so actually it's more like 175 dpi but that doesn't matter much).

corsac at scapa: printenv |grep -c GDK
0
dump_xsettings|grep -ci GDK
0

So as far as I can tell the Xft/DPI xsettings is correctly set (whether
I'm overriding the DPI in xfconf or not).
