 * @image latex img/widget/win/preview-00.eps
 *
 * The window class of Elementary. Contains functions to manipulate
 * windows. The Evas engine used to render the window contents is specified
 * in the system or user elementary config files (whichever is found last),
 * and can be overridden with the ELM_ENGINE environment variable for
 * testing.  Engines that may be supported (depending on Evas and Ecore-Evas
 * compilation setup and modules actually installed at runtime) are (listed
 * in order of best supported and most likely to be complete and work to
 * lowest quality).
 *
 * @li "x11", "x", "software-x11", "software_x11" (Software rendering in X11)
 * @li "gl", "opengl", "opengl-x11", "opengl_x11" (OpenGL or OpenGL-ES2
 * rendering in X11)
 * @li "shot:..." (Virtual screenshot renderer - renders to output file and
 * exits)
 * @li "fb", "software-fb", "software_fb" (Linux framebuffer direct software
 * rendering)
 * @li "sdl", "software-sdl", "software_sdl" (SDL software rendering to SDL
 * buffer)
 * @li "gl-sdl", "gl_sdl", "opengl-sdl", "opengl_sdl" (OpenGL or OpenGL-ES2
 * rendering using SDL as the buffer)
 * @li "gdi", "software-gdi", "software_gdi" (Windows WIN32 rendering via
 * GDI with software)
 * @li "dfb", "directfb" (Rendering to a DirectFB window)
 * @li "x11-8", "x8", "software-8-x11", "software_8_x11" (Rendering in
 * grayscale using dedicated 8bit software engine in X11)
 * @li "x11-16", "x16", "software-16-x11", "software_16_x11" (Rendering in
 * X11 using 16bit software engine)
 * @li "wince-gdi", "software-16-wince-gdi", "software_16_wince_gdi"
 * (Windows CE rendering via GDI with 16bit software renderer)
 * @li "sdl-16", "software-16-sdl", "software_16_sdl" (Rendering to SDL
 * buffer with 16bit software renderer)
 * @li "ews" (rendering to EWS - Ecore + Evas Single Process Windowing System)
 * @li "gl-cocoa", "gl_cocoa", "opengl-cocoa", "opengl_cocoa" (OpenGL rendering in Cocoa)
 * @li "psl1ght" (PS3 rendering using PSL1GHT)
 *
 * All engines use a simple string to select the engine to render, EXCEPT
 * the "shot" engine. This actually encodes the output of the virtual
 * screenshot and how long to delay in the engine string. The engine string
 * is encoded in the following way:
 *
 *   "shot:[delay=XX][:][repeat=DDD][:][file=XX]"
 *
 * Where options are separated by a ":" char if more than one option is
 * given, with delay, if provided being the first option and file the last
 * (order is important). The delay specifies how long to wait after the
 * window is shown before doing the virtual "in memory" rendering and then
 * save the output to the file specified by the file option (and then exit).
 * If no delay is given, the default is 0.5 seconds. If no file is given the
 * default output file is "out.png". Repeat option is for continuous
 * capturing screenshots. Repeat range is from 1 to 999 and filename is
 * fixed to "out001.png" Some examples of using the shot engine:
 *
 *   ELM_ENGINE="shot:delay=1.0:repeat=5:file=elm_test.png" elementary_test
 *   ELM_ENGINE="shot:delay=1.0:file=elm_test.png" elementary_test
 *   ELM_ENGINE="shot:file=elm_test2.png" elementary_test
 *   ELM_ENGINE="shot:delay=2.0" elementary_test
 *   ELM_ENGINE="shot:" elementary_test
 *
 * Signals that you can add callbacks for are:
 *
 * @li "delete,request": the user requested to close the window. See
 * elm_win_autodel_set().
 * @li "focus,in": window got focus
 * @li "focus,out": window lost focus
 * @li "moved": window that holds the canvas was moved
 * @li "withdrawn": window is still managed normally but removed from view
 * @li "iconified": window is minimized (perhaps into an icon or taskbar)
 * @li "normal": window is in a normal state (not withdrawn or iconified)
 * @li "stick": window has become sticky (shows on all desktops)
 * @li "unstick": window has stopped being sticky
 * @li "fullscreen": window has become fullscreen
 * @li "unfullscreen": window has stopped being fullscreen
 * @li "maximized": window has been maximized
 * @li "unmaximized": window has stopped being maximized
 *
 * Examples:
 * @li @ref win_example_01
