Workaround the issue + some improvements

This should help, it also includes a couple of fixes (aka that's how it should
have been in the first place). I'll rework this a bit before submitting to
wine-patches, maybe introducing a new WINED3DFMT_FLAG to mark those formats
which should be tested on DX10+ GPUs.
