I must ask a security question; to what extent has the imblib image
rendering code (and libraries used) been security audited?

Whilst I am on the topic of security, can someone confirm my initial
impression of the gdmgreeter security model?

My understanding is this: gdmgreeter is spawned by gdm. gdmgreeter runs as
a non-root user. gdmgreeter is untrusted by gdm (which runs as root).
gdmgreeter passes the intended user, password and session back to the
parent process, gdm, which does all the authentication itself.
