   2  * Unit tests for ddraw functions
   3  *
   4  *
   5  * Part of this test involves changing the screen resolution. But this is
   6  * really disrupting if the user is doing something else and is not very nice
   7  * to CRT screens. Plus, ideally it needs someone watching it to check that
   8  * each mode displays correctly.
   9  * So this is only done if the test is being run in interactive mode.
