add cohenSutherland break for case that was causing infinite loop

[jeffbl]

This causes diagrams to completely fail, so I'm going to merge this tentative fix, but this should really be looked at in more detail. Tested on unicorn with override, and it prevents the timeout, but I do not know the implications to the actual rendering.

TLDR: adds a break for a loop that never exited, causing timeouts and lack of any tactile rendering.

resolves #1186 , which describes the fix and potential implications
