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