Well, it's not that simple. For the really-internal tasks, I have
now add support to the trunk, 1.3 branch and 1.2 branch to avoid them
by default. For the "acquire" tasks, these are actually introduced
by the application, by the RUNTIME_desc_acquire() call made to fetch
data back on CPUs, so by default we do want to show them since that's
actually from the application. I have however now added a -no-acquire
option to ignore them. That may however produce odd results if several
computations are performed on the same data with acquisitions in
between.

> — also, how can I change colors?

By default in dag.dot the colors correspond to the worker which ran
the tasks. I have now added color fields to the task and the codelet
structures.
