5 This test makes sure that scrolling a huge canvas would correctly scroll
6 its contents. We don't accelerate extremely large canvases because of
7 GPU maximum texture size limits, so this test makes sure that the
8 non-accelerated code path for this operation works correctly.
10 The padding in this test is added mostly to make sure that scrollLeft/Top
11 correctly skip the padding.
