// HAXX: zcomploc is a way to control whether depth test is done before

// not updated during shader execution. but GC hardware acts different:
// if zcomlock is enabled, depth value is updated even if alpha test fails
// not updated during shader execution.
// We implement "depth test before texturing" by discarding the fragment
// when the alpha test fail. This is not a correct implementation because
// even if the depth test fails the fragment could be alpha blended.

// 1 - if zcomplock is enabled make a last pass, with color channel write disabled updating only
