commit 0f7339404ba391a26047ddc3fe0272812e84a3cf
Author: Damian Johnson <atagar at torproject.org>
Date: Wed Jul 13 09:04:15 2016 -0700
Drop legacy draw method
Now that all our panels use the new draw() function the other condition is dead
code. This in turns means we can drop the force flag since it's unused.
