TEST 1: sanity check prog_vs_fs
TEST 2: bad: prog_gs in the middle of prog_vs_fs
Failed to validate the pipeline: error: Program object is active for a stage between two stages for which another program object is active
TEST 3: bad: prog_fs and  only VS of prog_vs_fs
Failed to validate the pipeline: error: Program object is not active for all stages for which it contains executable code
TEST 4: good: prog_vs_fs in 2 step
TEST 5: bad: prog_gs without prog_vs
Failed to validate the pipeline: error: Program pipeline object contains an active geometry program, but no active vertex program
TEST 6: bad: only GS of prog_vs_gs
!!! Wrong pipeline validation status. Got 1, expected 0

TEST 7: good: sanity check all single prog
TEST 8: bad: prog_tcs in the middle of prog_vs_gs

TEST 9: bad: prog_tes in the middle of prog_vs_gs
Failed to validate the pipeline: error: Program object is active for a stage between two stages for which another program object is active
TEST 10: bad: only tes of prog_tess
!!! Wrong pipeline validation status. Got 1, expected 0

TEST 11: bad: prog_tess without prog_vs
Failed to validate the pipeline: error: Program pipeline object contains an active tesselation control program, but no active vertex program
error: Program pipeline object contains an active tesselation evaluation program, but no active vertex program
