Okay, it's time for me to speak up.
I "sabotaged" this entire effort. You see, five years ago, I had a
laptop with a brand-spanking-new Radeon X1650. Only fglrx was
available. fglrx used the actual screen DPI, causing all of my fonts
to be stupidly large; from login to logout all of my glyphs appeared
to be anti-aliased Michelin men. When the open drivers started to pick
up support for my chipset, I couldn't help but notice that all of my
lettering suddenly reverted to a reasonable size. From then on, I
vowed that I would never let the bloated, oversized fonts taint my
screen, nor anybody else's screens, ever again.
So for the past half-decade I've waged a secret war, carefully
manipulating key members of the X.org team in order to protect the 96
DPI "standard" in the name of small fonts everywhere. I feel only
small amounts of shame at this revelation; I regret nothing.
