-// Screen represents the physical (or emulated) screen.
-// This can be a terminal window or a physical console.  Platforms implement
-// this differerently.
-type Screen interface {
-	// Init initializes the screen for use.
-	Init() error
-
-	// Fini finalizes the screen also releasing resources.
-	Fini()
-
-	// Clear erases the screen.  The contents of any screen buffers
-	// will also be cleared.  This has the logical effect of
-	// filling the screen with spaces, using the global default style.
-	Clear()
-
-	// Fill fills the screen with the given character and style.
-	Fill(rune, Style)
-
-	// SetCell is an older API, and will be removed.  Please use
-	// SetContent instead; SetCell is implemented in terms of SetContent.
-	SetCell(x int, y int, style Style, ch ...rune)
-
-	// GetContent returns the contents at the given location.  If the
-	// coordinates are out of range, then the values will be 0, nil,
-	// StyleDefault.  Note that the contents returned are logical contents
-	// and may not actually be what is displayed, but rather are what will
-	// be displayed if Show() or Sync() is called.  The width is the width
-	// in screen cells; most often this will be 1, but some East Asian
-	// characters require two cells.
-	GetContent(x, y int) (mainc rune, combc []rune, style Style, width int)
-
-	// SetContent sets the contents of the given cell location.  If
-	// the coordinates are out of range, then the operation is ignored.
-	//
-	// The first rune is the primary non-zero width rune.  The array
-	// that follows is a possible list of combining characters to append,
-	// and will usually be nil (no combining characters.)
-	//
-	// The results are not displayd until Show() or Sync() is called.
-	//
-	// Note that wide (East Asian full width) runes occupy two cells,
-	// and attempts to place character at next cell to the right will have
-	// undefined effects.  Wide runes that are printed in the
-	// last column will be replaced with a single width space on output.
-	SetContent(x int, y int, mainc rune, combc []rune, style Style)
-
-	// SetStyle sets the default style to use when clearing the screen
-	// or when StyleDefault is specified.  If it is also StyleDefault,
-	// then whatever system/terminal default is relevant will be used.
-	SetStyle(style Style)
-
-	// ShowCursor is used to display the cursor at a given location.
-	// If the coordinates -1, -1 are given or are otherwise outside the
-	// dimensions of the screen, the cursor will be hidden.
-	ShowCursor(x int, y int)
-
-	// HideCursor is used to hide the cursor.  Its an alias for
-	// ShowCursor(-1, -1).
-	HideCursor()
-
-	// Size returns the screen size as width, height.  This changes in
-	// response to a call to Clear or Flush.
-	Size() (int, int)
-
-	// PollEvent waits for events to arrive.  Main application loops
-	// must spin on this to prevent the application from stalling.
-	// Furthermore, this will return nil if the Screen is finalized.
-	PollEvent() Event
-
-	// PostEvent tries to post an event into the event stream.  This
-	// can fail if the event queue is full.  In that case, the event
-	// is dropped, and ErrEventQFull is returned.
-	PostEvent(ev Event) error
-
-	// PostEventWait is like PostEvent, but if the queue is full, it
-	// blocks until there is space in the queue, making delivery
-	// reliable.  However, it is VERY important that this function
-	// never be called from within whatever event loop is polling
-	// with PollEvent(), otherwise a deadlock may arise.
-	//
-	// For this reason, when using this function, the use of a
-	// Goroutine is recommended to ensure no deadlock can occur.
-	PostEventWait(ev Event)
-
-	// EnableMouse enables the mouse.  (If your terminal supports it.)
-	EnableMouse()
-
-	// DisableMouse disables the mouse.
-	DisableMouse()
-
-	// HasMouse returns true if the terminal (apparently) supports a
-	// mouse.  Note that the a return value of true doesn't guarantee that
-	// a mouse/pointing device is present; a false return definitely
-	// indicates no mouse support is available.
-	HasMouse() bool
-
-	// Colors returns the number of colors.  All colors are assumed to
-	// use the ANSI color map.  If a terminal is monochrome, it will
-	// return 0.
-	Colors() int
-
-	// Show makes all the content changes made using SetContent() visible
-	// on the display.
-	//
-	// It does so in the most efficient and least visually disruptive
-	// manner possible.
-	Show()
-
-	// Sync works like Show(), but it updates every visible cell on the
-	// physical display, assuming that it is not synchronized with any
-	// internal model.  This may be both expensive and visually jarring,
-	// so it should only be used when believed to actually be necessary.
-	//
-	// Typically this is called as a result of a user-requested redraw
-	// (e.g. to clear up on screen corruption caused by some other program),
-	// or during a resize event.
-	Sync()
-
-	// CharacterSet returns information about the character set.
-	// This isn't the full locale, but it does give us the input/output
-	// character set.  Note that this is just for diagnostic purposes,
-	// we normally translate input/output to/from UTF-8, regardless of
-	// what the user's environment is.
-	CharacterSet() string
-
-	// RegisterRuneFallback adds a fallback for runes that are not
-	// part of the character set -- for example one coudld register
-	// o as a fallback for ø.  This should be done cautiously for
-	// characters that might be displayed ordinarily in language
-	// specific text -- characters that could change the meaning of
-	// of written text would be dangerous.  The intention here is to
-	// facilitate fallback characters in pseudo-graphical applications.
-	//
-	// If the terminal has fallbacks already in place via an alternate
-	// character set, those are used in preference.  Also, standard
-	// fallbacks for graphical characters in the ACSC terminfo string
-	// are registered implicitly.
-
-	// The display string should be the same width as original rune.
-	// This makes it possible to register two character replacements
-	// for full width East Asian characters, for example.
-	//
-	// It is recommended that replacement strings consist only of
-	// 7-bit ASCII, since other characters may not display everywhere.
-	RegisterRuneFallback(r rune, subst string)
-
-	// UnregisterRuneFallback unmaps a replacement.  It will unmap
-	// the implicit ASCII replacements for alternate characters as well.
-	// When an unmapped char needs to be displayed, but no suitable
-	// glyph is available, '?' is emitted instead.  It is not possible
-	// to "disable" the use of alternate characters that are supported
-	// by your terminal except by changing the terminal database.
-	UnregisterRuneFallback(r rune)
-
-	// CanDisplay returns true if the given rune can be displayed on
-	// this screen.  Note that this is a best guess effort -- whether
-	// your fonts support the character or not may be questionable.
-	// Mostly this is for folks who work outside of Unicode.
-	//
-	// If checkFallbacks is true, then if any (possibly imperfect)
-	// fallbacks are registered, this will return true.  This will
-	// also return true if the terminal can replace the glyph with
-	// one that is visually indistinguishable from the one requested.
-	CanDisplay(r rune, checkFallbacks bool) bool
-
-	// Resize does nothing, since its generally not possible to
-	// ask a screen to resize, but it allows the Screen to implement
-	// the View interface.
-	Resize(int, int, int, int)
-
-	// HasKey returns true if the keyboard is believed to have the
-	// key.  In some cases a keyboard may have keys with this name
-	// but no support for them, while in others a key may be reported
-	// as supported but not actually be usable (such as some emulators
-	// that hijack certain keys).  Its best not to depend to strictly
-	// on this function, but it can be used for hinting when building
-	// menus, displayed hot-keys, etc.  Note that KeyRune (literal
-	// runes) is always true.
-	HasKey(Key) bool
