As a teacher I can think of some more Applications. Of course, these are
pedagogical:
Teaching scripts to beginners (learning to write a primary school,
learning to write in a different script when learning another language
(or even in the same language: Mongol?):
You might want to color single parts of a glyph in order to highlight
them. So, for example in a handwritten (see
http://de.wikipedia.org/wiki/Schulausgangsschrift or english equivalents
I haven't found in the time) "a" the beginning or end-strokes might be
colored.
Of course the font creator has to create sub-glyphs or other fancy
stufff, but XeTeX should allow (re)composition of the glyph with
different colors.

Thanks, Khaled.
I realize the limitations etc.--just thought I'd note that these things
are in some measure possible, if one wishes to implement them (not that
one 'should', necessarily). In particular with regards to some recent
posts, I seem to remember that glyph sub-definition was not limited to
horizontal slices, either: one could define sub-bounding boxes of
whatever type. (And with WorldPad, the cursor could be placed within
glyphs, too, I think...)

OpenType has ligature caret info (in GDEF table) but is less

very few fonts, if any, have it.

I seem to recall from the days when I was doing demos/mock-ups for
the
cuneiform encoding proposal that SIL's graphite/WorldPad combo
allowed
one to do things of this sort; it involved specifying sub-areas in
special font tables, which the software of course had to know
about.
Not sure whether that's useful to this discussion, but thought I'd
mention it.

In this case FireFox colourises half of resulting ff ligatures
(1/3
in
ffi etc), I'm not sure how this is done or if it is possible with
PDF
at
all, but that is of limited value anyway specially for ligatures
that
can not be split vertically or into equal parts (ligatures carets
might
provide a clue in the later case, but they are rarely provided by
font
developers).
