test case

With i915 driver, we got result:

draw pixel at (0, 0): 0.000000 0.000000 0.000000
draw pixel at (1, 0): 0.000000 0.000000 0.000000
draw pixel at (2, 0): 0.000000 0.000000 0.000000

It should be: (got with i965 driver)

draw pixel at (0, 0): 1.000000 0.000000 0.000000
draw pixel at (1, 0): 1.000000 0.000000 0.000000
draw pixel at (2, 0): 0.000000 0.000000 0.000000

Mass version move, cvs -> git
