The ability to control the opacity of a logo from the telnet/rc interface does not appear to work in 2.1.
The GUI control does work in 2.1 and the telnet/rc interface did work in 2.0.8 (and 2.0.5 and 1.1.11 and ...).
I have been using a Python telnet connection for years to manage this.
Where (in the source) should I be looking for this? Or is this a lua change?
