[PATCH 1/2] d3d9/tests: Port test_flip to d3d9.

[Stefan Dösinger]

This only tests cycling through the backbuffers. Like it's ddraw
counterpart it doesn't test for the front buffer to come out at the
other end of the flip chain. I don't think we want to bother about this
until we have an application that really needs this.

A d3d8 version of this test will follow. Partial presents (RECT or
region parameters in Present) are only valid if the swap effect is COPY.
In this case the back buffer count is forced to be 1 and no buffer
cycling, flipping etc will happen. A test for that will follow.
