Well, the patch has been committed but the ok() message looks a bit 
strange now. Do you think it makes sense to change getdc_capable to a 
HRESULT and do something like the following instead:

ok(hr == testdata[i].result ||
    testdata[i].alt_result && hr == testdata[i].alt_result,
    "GetDC on a %s surface returned 0x%08\n",
    testdata[i].name, hr);

Default result should be S_OK when capable and DDERR_CANTCREATEDC when not.

One thing I saw by running the above is that we return E_INVALIDARG 
instead of DDERR_CANTCREATEDC when GetDC fails btw.
