*
* struct Goku {
* vec4 gohan;
* vec4 goten;
* vec4 chichi;
* };
*
* layout (xfb_offset = 16) out Goku goku;
*
* goku.gohan = EXPECTED_VALUE;
* goku.chichi = EXPECTED_VALUE;
*
* Test pass when captured values of gohan and chichi match expected values.
* It is expected that goten will receive undefined value.
*
* Test all shader stages.
