Fix frame_rate_tests for Vista.

Fix frame_rate_tests for Vista.

chrome on Vista uses accelerated canvas even without accelerated compositing. So to force software, we need --disable-accelerated-2d-canvas.

Additionally, to avoid potential flakiness, moved the check from context creation success to actual swap buffers - that way if someone creates a context without drawing, it will not trigger.

lgtm

How did this not pop on the other platforms?

No clue. Still need to look into it.
