v1.1.0 Bug fixes

- Abandons window rendering. Rendering the strings to the background are
  sufficient.
  - Clearly I'm not understanding something or I'm mis-using the library.
    Rendering the window tile messes up the background layer.
- Pause menu and grid rendering finally fixed. Aesthetically, the game looks
  a lot better
