Ah, however, - shifting goalposts a little - still confused why there is the
variation.. 
* 7,01 cm on dialog initialization. And 6,98 cm after bumping DPI to 97 and
back to 96. If this is a rounding should end up this way, please make it
consistent.
* And even worse in case of switching from DPI to Pixel to CM. Where moving 37
Pixel the CM up to 38 and back to 37 end up with 7,16 CM not 7,01 cm
