As a natural and plentiful supply of Dried Frog Pills (TM) is becoming more
scarce and illicit as the decades whiz by, errant thoughts on various subjects
and POV-Ray such as the following continually fill my mind:

The lettering on road surfaces is a vertically stretched typeface, to compensate
for the somewhat extreme viewing angle from the driver's seat.

I have not seen any specifications for these letters and arrows, and have not
yet found a source to download such a font / typeface.

Doing a bit of trigonometric scribbling, at first glance it appears that the
upper half and lower half of such a typeface [ideally] ought to be scaled to
different extents.

So my questions are:
a) can anyone dig up DOT specs?
b) Are such fonts available for download?
c) What's the best way to display a text{} object such that the bottom half and
top half are unequally scaled?
(I'm thinking CSG-type cropping, or something like Dave Blandston's excellent
work with text)

I'll likely work up some diagrams and equations, but I figured I'd just throw
this out there for fun.
