// These enums & structures are copied from GSdx, which got them from sp2dev 0.4.0.

// In fact, after looking at both ZeroGS and GSdx, and seeing how similar this section is on both,
// I'm just going to blatantly copy most of GS.h here and localize.

// And if this is kept close enough to GSdx's code, if should make porting GSdx to Linux a bit easier...
