[PATCH 1/2] d3d11/tests: Added more multisample resolve tests.

[Jan Sikorski]

Hi Stefan,
Thank you for nitpicking ;) I’ll comply and resend after I get feedback on the other patch too.
I don’t love the idea of merging these tests though. They are not fully orthogonal, but don’t exactly do the same thing either, and I don’t see what’s to gain by messing with the old one. I’m flexible on the naming though - how about multisample_resolve_blended? The main difference is that I set it up to take one sample from geometry and the other one from the background.
One more thing I’m on the fence about is baking in some tolerance for the results. Right now some of the tests fail because I check the values exactly.
