** Mitigated by patch that removes mipmapping
*** Renders fine but godrays from windows are removed because they depend on mipmaps being emulated
**** Renders fine but you lose spotlight lighting

These same issues happen with both GSdx and parallel-gs.

Start by reproducing the listed games with the mipmap-unclamped setting in both GSdx and parallel-gs. Compare the noted rendering effects and existing patches, then determine a concrete, testable fix for the affected games; done means the listed mipmap-related problems are resolved without the documented visual regressions.
