  -- | Gloss hides the pain of drawing simple vector graphics behind a nice data type and
  --      a few display functions.
  --
  --   Getting something on the screen is as easy as:
  --
  --  @
  --  import Graphics.Gloss
  --  main = `display` (InWindow \"Nice Window\" (200, 200) (10, 10)) `white` (`Circle` 80)
  --  @
  --
  --   Once the window is open you can use the following:
  --
  -- @
  -- * Quit
  --   - esc-key
  --
  -- * Move Viewport
  --   - arrow keys
  --   - left-click drag
  --
  -- * Zoom Viewport
  --   - page up/down-keys
  --   - control-left-click drag
  --   - right-click drag
  --   - mouse wheel
  --
  -- * Rotate Viewport
  --   - home/end-keys
  --   - alt-left-click drag
  --
  -- * Reset Viewport
  --   'r'-key
  -- @
  --
  --
  --   Animations can be constructed similarly using the `animate`.
  --
  --   If you want to run a simulation based around finite time steps then try
  --   `simulate`.
  --
  --   If you want to manage your own key\/mouse events then use `play`.
  --
  --   Gloss uses OpenGL under the hood, but you don't have to worry about any of that.
  --
  --   Gloss programs should be compiled with @-threaded@, otherwise the GHC runtime
  --   will limit the frame-rate to around 20Hz.
  --
  --   To build gloss using the GLFW window manager instead of GLUT use
  --        @cabal install gloss --flags=\"GLFW -GLUT\"@

  -- Release Notes:
  --
  --  For 1.13.1:
  --   Thanks to Thaler Jonathan
  --   * Repaired GLFW backend.
  --   Thanks to Samuel Gfrörer
  --   * Support for bitmap sections.
  --   Thanks to Basile Henry
  --   * Handle resize events in playField driver.
  --
  --  For 1.12.1:
  --   Thanks to Trevor McDonell
  --   * Travis CI integration, general cleanups.
  --
  --  For 1.11.1:
  --   Thanks to Lars Wyssard
  --   * Use default display resolution in full-screen mode.
  --
  --  For 1.10.1:
  --   * Gloss no longer consumes CPU time when displaying static pictures.
  --   * Added displayIO wrapper for mostly static pictures, eg when
  --     plotting graphs generated from infrequently updated files.
  --   * Allow viewport to be scaled with control-left-click drag.
  --   * Rotation of viewport changed to alt-left-click drag.
  --   * Preserve current colour when rendering bitmpaps.
  --   * Changed to proper sum-of-squares colour mixing, rather than naive
  --     addition of components which was causing mixed colours to be too dark.
  --  Thanks to Thomas DuBuisson
  --   * Allow bitmaps to be specified in RGBA byte order as well as ABGR.
  --  Thanks to Gabriel Gonzalez
  --   * Package definitions for building with Stack.
