[PATCH 1/5] dxgi/tests: Test fullscreen and multiple swapchains.

[Stefan Dösinger]

Contrary to the d3d8/9 behavior, fullscreen swapchains can be created
while a windowed swapchain exists. Creating a windowed (or fullscreen)
swapchain while a fullscreen one exists is not allowed.

Setting the swapchains to windowed mode before destroying them is
necessary to avoid a segfault on native.
