tests: Add test_window_basic

Moguri · rdb · commit aabf009ff046 · 2017-11-03T19:25:13.000+01:00
This test just makes sure that created windows match the default
WindowProperties (with a few exceptions).

This also adds the following fixtures:

  * graphics_engine - scope='session', GraphicsEngine
  * graphics_pipe - scope='session', default GraphicsPipe
  * window - scope='test', GraphicsWindow with default framebuffer and window properties
