Vulkan 1.1 spec section 15.6.7. Scale Factor Operation, Level-of-Detail
Operation and Image Level(s) Selection clarifies that the first returned
parameter is the clamped LOD, rounded to the nearest integer if
mipmapMode is VK_SAMPLER_MIPMAP_MODE_NEAREST, and the second parameter
is the unclamped LOD with base level and sampler bias applied (we don't
take maxSamplerLodBias into account, it is infinite).
