It's probably fine to add the required feature level to the
"texture_tests" array but make sure that it's optional. The other
option (which has some advantages) is to simply hardcode the formats
and required feature levels in the for loop, i.e. add a condition
similar to "if (... && test->texture->format == ... && feature_level <
...)".

Increasing the range to +- 2 should be ok.
