DPI is mostly for applications which need to draw things of known size
(e.g. maps), so reporting wrong DPI is just brain-damaged.

Corellation between DPI and fonts size is the unfortunate artifact of fonts
implementation, and MUST be corrected at the fontconfig side (I'm pretty sure it
can be fixed just in fonts.conf).

Reporting wrong DPI might have the same effect as stupid widget systems on
Windows - do you know why most of the displays on the market have such low DPI?
Just because Windows applications can't adjust to the higher DPI, so hardware
manufactures are forced to create 75-100 DPI displays (and software developers
have to deal with subpixel rendering as the consequence)..

ps: 3rd-party binary-only crap is the biggest handbrake of engineering.
