  What you are looking for is the holy grail of raytracing. Unfortunately
it's not possible in general (even though it may be possible in very
specific cases; font's *might* be such a case, but I wouldn't bet on it).

  A (fast) distance-from-object-surface function would be the holy grail
of raytracing because it would allow easy non-linear transformations and
other nice effects. Unfortunately it's not that easy.
