Overview

A Tile stores all attributes required by a Viewport to draw it. ‘Tile.new` takes an `args` hash as its only parameter. The `args` hash respects three members:

* `:glyph`: The unicode character. _Defaults to `' '`._

* `:foreground`: The foreground color represented by a `Gosu::Color`
instance. _Defaults to `DEFAULT_FOREGROUND`._

* `:background`: The background color represented by a `Gosu::Color`
instance. _Defaults to `DEFAULT_BACKGROUND`._
