2 | ZCOMP_EQUAL | Test will only succeed if the z value of the pixel to be drawn is equal to the value of the previous drawn pixel.
3 | ZCOMP_LESS_EQUAL | Test will succeed if the z value of the pixel to be drawn is smaller than or equal to the value in the Z Buffer.
4 | ZCOMP_GREATER | Opposite of TEST_LESS.
5 | ZCOMP_NOT_EQUAL | Test will succeed if the z value of the pixel to be drawn is NOT equal to the value of the previously drawn pixel.
