I can't think of any cases where you want the font DPI to follow what
the monitor reports. There are two possibilities:

 A) The monitor is wrong (happens frequently)
 
 B) The monitor is right

In B) you'd think you'd want to use the resolution, but actually:

 * It's not what user's want. User's typically, when they reduce
   the resolution, do that to make fonts (etc.) bigger.

 * Angular resolution is far more important than linear resolution;
   you don't want 3pt fonts on your 10-foot projection screen

In the ideal world of 200dpi screens and all graphics scalable,
DPI will become a simpler thing to manage - though still it's really
the overall "scale" and that won't necessarily correspond to physical
DPI. But in the current world, keeping the point_size => pixel number
fixed at 96 is right for most users, and letting it be set manually
should be sufficient power for the rest.
