MSDN for IDirect3D9_EnumAdapterModes() also seems to hint that
D3DFMT_R5G6B5, D3DFMT_X1R5G5B5 and D3DFMT_A1R5G5B5 are supposed to be
equivalent as far as display modes are concerned. This may be a quirk
of the AMD driver, but I don't have a lot of Windows or NVIDIA systems
to really compare.

> Do you think I should just ignore "nmodes" for windowed mode?  It seems like the test is saying that CheckDeviceType() doesn't care whether the display format is supported for windowed mode.  Of course, it's unreliable to extrapolate from a single data point.

I'm not sure.

Come to think about it, the broken() in this test is perhaps a bit
overly broad as well.

Yeah, it's nice for debugging now, but in the general case it just
makes it harder to spot failures.
