I've been trying to get even the simplest of shaders working with no success.
I've tried many things, starting with some tutorials which were terribly
outdated. This is where I'm at now. I set a break point in the .cpp in
DYNAMIC_STATE and it gets hit, so the codes getting called when I set it as the
overlay. The shader is getting loaded, since if I remove the .vcs, the game
complains that it can't find it. Other overlays work, like the combine vision.
So I'm at a loss. This started as a sepia overlay from a tut, but it's been
trimmed down to this. I've tried a few variations of parameters and return
types for the shader's main function. I also tried a vertex shader that just
copies the values, also with a few variations of parameters and return types.
