Well, strictly speaking, transset isn't a requirement.

Composite and the compositing manager make transparency possible, but
it actually isn't used by anything but the panel. transset is a
program that sets a Window Manager hint, which currently forces a
window to be transparent. It's a toy, applications should enable
transparency on their own if the app wants to use it.
