[Therion] Therion/loch crashes in sid (issue #158)

Hi Olly, i hope you can help me out with issue #158 (https://github.com/therion/therion/issues/158) I am fiddling around in hope to get my loch viewer working again. It worked in the past but then decided after a debian update to cease functioning because of failing glx context. I now have the impression, maybe wxWidgets is the cause. The glx context is fine, other X applications can successfully establish 3D perfomance and glx debug commands also tell me „ok“. I habe seen that there is a wxWidgets 3.1.4 out there. Maybe this could solve my issue? Can you please make me an updated debian package (or tell me how i can build it myself)?
