Set modifiers in a non-reactive manner

This should prevent modifier keys from getting 'stuck'. I don't know exactly how modifiers come to be stuck. But I've experienced it on multiple occasions. I've also seen reports of shift becoming stuck--mistaken for caps lock--becoming difficult to deduce.

changed the description

Does this code work for console window events (i.e. those of type ev_console)? IIRC the console window for dedicated mode handles key input somewhat differently, may not even involve SDL at all.

Btw, a console window can be made to pop up alongside the main SRB2 one if you use the -console param, where you can see what happens in-game when you do something in the species window. That might be useful for testing what I'm on about.

"species"? I mean "special", I've been spending too much on Wikipedia clearly.

*too much time

ev_console is always straight from stdin--the terminal controller handles modifier keys.

No problems here +1

We do not care for the old DirectX interface, so I say +1
