Berthold Stoeger ae1758d4cd profile: don't render mobile profile in printmode
There is no more reason to render the profile in printMode.
DPR is also supported in normal mode.

Moreover, don't scale the DPR down by fontScale. If we
have to scale down the fonts, we'll have to do this
differently without squeezing the rest of the profile
features.
