Pardon my curiosity, but what is the significance of the OS knowing the
PPI of the screen?  Consider the following scenarios:

Screen #1 is an independent monitor: a 19" LCD with native 1280x1024
resolution.  The PPI is approx. 85.  The user sits between 3 and 5 feet
away from this screen.

Screen #2 is a laptop panel: a 14.1" LCD with native 1280x800
resolution.  The PPI is approx. 105.  The user sits between 1 and 2 feet
away from this screen.

When the GUI scales everything by the DPI of the monitor, it will scale
everything according to what the "real" size of the graphics should be.
This means that Screen #1 will display more information on it than
Screen #2, regardless of resolution.  However, the smaller size of the
graphics on Screen #1 causes the user to strain at his usual sitting
distance from the monitor, while the relatively large graphics on Screen
#2 suffocate him with their sheer size.

I guess what I'm asking is, wouldn't it make more sense to have a GUI
scaling tool that lets you resize all graphics (independent of
resolution) rather than autosize everything according to the monitor's
PPI?
