Bug#1101174: dhewm3: enable new imgui based menu

Hi Tobias,

There is a newer imgui package in experimental, and it can be used to 
enable the new setting menu in dhewm3.
It needs some tweak to the code, but the good news is that I can offer 
you a MR that takes care of everything:
https://salsa.debian.org/games-team/dhewm3/-/merge_requests/6

It would be great if you could manage to merge this and upload a test 
build to experimental :-)

best regards,
Sébastien
