Remove backbuffer comparisons from test suite, simplify default triangle

* It's not particularly scalable and can be brittle to driver changes, and we
  can use targeted specific pixel tests to check what we really want - to see if
  the output has rendered correctly.
* Overlay tests still check files directly - this is a future refactor to
  remove.
