konstructs
Detect and display info about old OpenGL versions.
Find a good cross platform way to display a non-OpenGL GUI-dialogue that informs the user that the game require at least OpenGL 3.3.
Ref #223 and #219
https://github.com/aaronmjacobs/Boxer is an interesting choice to try out. But it only supports Windows, GTK 3 and OSX.
Do we like to have a hard dependency on GTK 3? I guess it's fine consider that most people will probably have that. Finally, it would be nice to have a fallback solution (maybe just use stdout) for other platforms like FreeBSD, define or compile flag will probably do just fine.
How 'bout putting this in the readme of the repository? It's a bit frustrating to just have a segfault immediately upon startup. All I can execute is ./konstructs -h - but that help message also doesn't specify that I needed OpenGL 3.3
