    -- | 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.
