--- Comment #8 from Ian Romanick idr@freedesktop.org --- The problem is that you can have comments *before* the #version line. Because of that (and every other vendor has implemented line continuation in some form since forever), Khronos decided to make the change retroactive. This shader in this game is *the* reason we added the driconf option. :)
