Devices like the Eee PC only support up to 800x480, but in that case
creating the device should simply fail, and skip the test, so in that
regard the test should be fine. The error that gets printed in
probably a flaw in our handling of multiple swapchains. As long as the
test doesn't fail because of it it's probably not a concern for now.
You should check the return values for CreateAdditionallSwapChain and
GetScissorRect though.
