IVA props can be clicked through the big map window

Parts can't, so it might just be a layer thing?

I tried putting the map on the mainCanvas instead of the dialogCanvas, no luck.

TUFX doesn't allow clicking through to props but I couldn't easily figure out what the differences are (TUFX uses imgui but has a ugui window that follows it around as well).
