Sure, this works OK in GNUplot, but not so nice in FLTK as the glyph
renderer produces hickups on control characters like \n, \t, \r, ..... and
on text cell arrays.

A while ago I've sent patches for this to the bug tracker (#31468) for both
__ axis_label__.m  (proposed earlier on by David Bateman) &
src/txt-eng-ft.cc (the actual glyph renderer).
Hopefully they'll be applied soon or perhaps someone can turn them into a
changeset (I'm still trying to find out how to do this myself easily, esp.
backing out).
