Indeed, these are two different things.  What I tried to point out was
that students normally don't reach the level of understanding the
FreeType code so that they are wondering how and where to add proper
tracing statements.

Regarding justification of adding a logging library I can only say
that it sounds like a good idea to me.  There are chances that the
GSoC project gets finished successfully (this is, the student did his
or her job well) but the code will be rejected later on because it
doesn't work as expected.  This might happen, but even then revisiting
the whole debugging stuff is a good thing: for example, it would also
be *very* helpful to get a better structure into the debugging output
(whatever such a structure would look like) to make it more readable –
and more consistent between the various font drivers.
