tdf#85761 vcl: JPEG export does not save PPI values correctly
JPEG values are currently hardcoded to 96PPI when we export JPEGs. The
Graphic class doesn't have an easy way to get the PPI, but this can
actually be calculated from the pref size and pref map mode (no idea
why it is called "Pref").
Interestingly, you need to get a multiplier to work this out, relative
to units of 100th mm. The EPS filter code had a function that does
exactly this, but it's entirely based on MapMode units so it was really
implemented in the wrong class IMO. I have thus moved it out of PSWriter
and into MapMode.
This also fixes tdf#65695, which was partially fixed, but had the JPEG
PPI hardcoded to 96dpi.
Also fixes tdf#97481.
