- Speed up MSAA by using custom resolve shaders instead of ID3D11DeviceContext::ResolveSubresource().
- Fix EFB access when MSAA is enabled.
- Implement the "force linear filtering" option.
- Compile shaders using shader model 4.1 or 5.0 if available.
- Some minor cleanups.

Who cares about DX9 and OGL anyway :P
