<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Tests: Refactor `Tests_Image_Functions::test_inferred_mime_types()` to use a data provider.
Using a data provider has a number of advantages:
1. If the first test case fails, it won't prevent the other test cases from being tested.
2. The output from PHPUnit will be more descriptive in case of failure when using a data provider.
3. Using named test cases in the data provider will also make the `--testdox` output much more descriptive and informative.
The actual cases being tested, or the test itself have not been changed.
Includes:
* Adding a `@covers` annotation.
* Adding a failure message to each assertion.
* Adding a skip annotation for unsupported mime types.
* Making the test method name more specific.
