/**
* Add (register) a callback function to a given canvas event.
*
* @param e Canvas to attach a callback to
* @param type The type of event that will trigger the callback
* @param func The (callback) function to be called when the event is
* triggered
* @param data The data pointer to be passed to @p func
*
* This function adds a function callback to the canvas @p e when the
* event of type @p type occurs on it. The function pointer is @p
* func.
*
* In the event of a memory allocation error during the addition of
* the callback to the canvas, evas_alloc_error() should be used to
* determine the nature of the error, if any, and the program should
* sensibly try and recover.
*
* A callback function must have the ::Evas_Event_Cb prototype
* definition. The first parameter (@p data) in this definition will
* have the same value passed to evas_event_callback_add() as the @p
* data parameter, at runtime. The second parameter @p e is the canvas
* pointer on which the event occurred. The third parameter @p
* event_info is a pointer to a data structure that may or may not be
* passed to the callback, depending on the event type that triggered
* the callback. This is so because some events don't carry extra
* context with them, but others do.
*
* The event type @p type to trigger the function may be one of
* #EVAS_CALLBACK_RENDER_FLUSH_PRE, #EVAS_CALLBACK_RENDER_FLUSH_POST,
* #EVAS_CALLBACK_CANVAS_FOCUS_IN, #EVAS_CALLBACK_CANVAS_FOCUS_OUT,
* #EVAS_CALLBACK_CANVAS_OBJECT_FOCUS_IN and
* #EVAS_CALLBACK_CANVAS_OBJECT_FOCUS_OUT. This determines the kind of
* event that will trigger the callback to be called. Only the last
* two of the event types listed here provide useful event information
* data -- a pointer to the recently focused Evas object. For the
* others the @p event_info pointer is going to be @c NULL.
*
* Example:
* @dontinclude evas-events.c
* @skip evas_event_callback_add(d.canvas, EVAS_CALLBACK_RENDER_FLUSH_PRE
* @until two canvas event callbacks
*
* Looking to the callbacks registered above,
* @dontinclude evas-events.c
* @skip called when our rectangle gets focus
* @until let's have our events back
*
* we see that the canvas flushes its rendering pipeline
* (#EVAS_CALLBACK_RENDER_FLUSH_PRE) whenever the @c _resize_cb
* routine takes place: it has to redraw that image at a different
* size. Also, the callback on an object being focused comes just
* after we focus it explicitly, on code.
*
* See the full @ref Example_Evas_Events "example".
*
* @note Be careful not to add the same callback multiple times, if
* that's not what you want, because Evas won't check if a callback
* existed before exactly as the one being registered (and thus, call
* it more than once on the event, in this case). This would make
* sense if you passed different functions and/or callback data, only.

Expose device (e.g. pen) axis information to applications Summary: This patch set adds the necessary code to expose device axis state to applications. This was primarily written with graphics tablets in mind, which -- in addition to acting like a mouse -- also provide information about pen pressure, tilt, etc. Other devices could potentially benefit from this API as well: touchscreens, joysticks, knob controllers, "spaceballs", etc. Whenever an update to the device state is recieved, an "Axis update" event is synthesized. This event contains the updated information, typically scaled and normalized to a particular logical range (e.g. zero to one for pressure, -pi to pi radians for angles, etc.). Information about the tool which generated the event is also stored so that applications can disambiguate events from multiple devices (or in the case of multitouch screens, individual fingers).

* #EVAS_CALLBACK_HOLD, #EVAS_CALLBACK_CHANGED_SIZE_HINTS,
* #EVAS_CALLBACK_IMAGE_PRELOADED or #EVAS_CALLBACK_IMAGE_UNLOADED.
*
* This determines the kind of event that will trigger the callback.
* What follows is a list explaining better the nature of each type of
* event, along with their associated @p event_info pointers:
*
* - #EVAS_CALLBACK_MOUSE_IN: @p event_info is a pointer to an
* #Evas_Event_Mouse_In struct\n\n
* This event is triggered when the mouse pointer enters the area
* (not shaded by other objects) of the object @p obj. This may
* occur by the mouse pointer being moved by
* evas_event_feed_mouse_move() calls, or by the object being shown,
* raised, moved, resized, or other objects being moved out of the
* way, hidden or lowered, whatever may cause the mouse pointer to
* get on top of @p obj, having been on top of another object
* previously.
*
* - #EVAS_CALLBACK_MOUSE_OUT: @p event_info is a pointer to an
* #Evas_Event_Mouse_Out struct\n\n
* This event is triggered exactly like #EVAS_CALLBACK_MOUSE_IN is,
* but it occurs when the mouse pointer exits an object's area. Note
* that no mouse out events will be reported if the mouse pointer is
* implicitly grabbed to an object (mouse buttons are down, having
* been pressed while the pointer was over that object). In these
* cases, mouse out events will be reported once all buttons are
* released, if the mouse pointer has left the object's area. The
* indirect ways of taking off the mouse pointer from an object,
* like cited above, for #EVAS_CALLBACK_MOUSE_IN, also apply here,
* naturally.
*
* - #EVAS_CALLBACK_MOUSE_DOWN: @p event_info is a pointer to an
* #Evas_Event_Mouse_Down struct\n\n
* This event is triggered by a mouse button being pressed while the
* mouse pointer is over an object. If the pointer mode for Evas is
* #EVAS_OBJECT_POINTER_MODE_AUTOGRAB (default), this causes this
* object to <b>passively grab the mouse</b> until all mouse buttons
* have been released: all future mouse events will be reported to
* only this object until no buttons are down. That includes mouse
* move events, mouse in and mouse out events, and further button
* presses. When all buttons are released, event propagation will
* occur as normal (see #Evas_Object_Pointer_Mode).
*
* - #EVAS_CALLBACK_MOUSE_UP: @p event_info is a pointer to an
* #Evas_Event_Mouse_Up struct\n\n
* This event is triggered by a mouse button being released while
* the mouse pointer is over an object's area (or when passively
* grabbed to an object).
*
* - #EVAS_CALLBACK_MOUSE_MOVE: @p event_info is a pointer to an
* #Evas_Event_Mouse_Move struct\n\n
* This event is triggered by the mouse pointer being moved while
* over an object's area (or while passively grabbed to an object).
*
* - #EVAS_CALLBACK_MOUSE_WHEEL: @p event_info is a pointer to an
* #Evas_Event_Mouse_Wheel struct\n\n
* This event is triggered by the mouse wheel being rolled while the
* mouse pointer is over an object (or passively grabbed to an
* object).
*
* - #EVAS_CALLBACK_MULTI_DOWN: @p event_info is a pointer to an
* #Evas_Event_Multi_Down struct
*
* - #EVAS_CALLBACK_MULTI_UP: @p event_info is a pointer to an
* #Evas_Event_Multi_Up struct
*
* - #EVAS_CALLBACK_MULTI_MOVE: @p event_info is a pointer to an
* #Evas_Event_Multi_Move struct

* - #EVAS_CALLBACK_AXIS_UPDATE: @p event_info is a pointer to an
* #Evas_Event_Axis_Update struct
*
* - #EVAS_CALLBACK_FREE: @p event_info is @c NULL \n\n
* This event is triggered just before Evas is about to free all
* memory used by an object and remove all references to it. This is
* useful for programs to use if they attached data to an object and
* want to free it when the object is deleted. The object is still
* valid when this callback is called, but after it returns, there
* is no guarantee on the object's validity.
*
* - #EVAS_CALLBACK_KEY_DOWN: @p event_info is a pointer to an
* #Evas_Event_Key_Down struct\n\n
* This callback is called when a key is pressed and the focus is on
* the object, or a key has been grabbed to a particular object
* which wants to intercept the key press regardless of what object
* has the focus.
*
* - #EVAS_CALLBACK_KEY_UP: @p event_info is a pointer to an
* #Evas_Event_Key_Up struct \n\n
* This callback is called when a key is released and the focus is
* on the object, or a key has been grabbed to a particular object
* which wants to intercept the key release regardless of what
* object has the focus.
*
* - #EVAS_CALLBACK_FOCUS_IN: @p event_info is @c NULL \n\n
* This event is called when an object gains the focus. When it is
* called the object has already gained the focus.
*
* - #EVAS_CALLBACK_FOCUS_OUT: @p event_info is @c NULL \n\n
* This event is triggered when an object loses the focus. When it
* is called the object has already lost the focus.
*
* - #EVAS_CALLBACK_SHOW: @p event_info is @c NULL \n\n
* This event is triggered by the object being shown by
* evas_object_show().
*
* - #EVAS_CALLBACK_HIDE: @p event_info is @c NULL \n\n
* This event is triggered by an object being hidden by
* evas_object_hide().
*
* - #EVAS_CALLBACK_MOVE: @p event_info is @c NULL \n\n
* This event is triggered by an object being
* moved. evas_object_move() can trigger this, as can any
* object-specific manipulations that would mean the object's origin
* could move.
*
* - #EVAS_CALLBACK_RESIZE: @p event_info is @c NULL \n\n
* This event is triggered by an object being resized. Resizes can
* be triggered by evas_object_resize() or by any object-specific
* calls that may cause the object to resize.
*
* - #EVAS_CALLBACK_RESTACK: @p event_info is @c NULL \n\n
* This event is triggered by an object being re-stacked. Stacking
* changes can be triggered by
* evas_object_stack_below()/evas_object_stack_above() and others.
*
* - #EVAS_CALLBACK_DEL: @p event_info is @c NULL.
*
* - #EVAS_CALLBACK_HOLD: @p event_info is a pointer to an
* #Evas_Event_Hold struct
*
* - #EVAS_CALLBACK_CHANGED_SIZE_HINTS: @p event_info is @c NULL.
*
* - #EVAS_CALLBACK_IMAGE_PRELOADED: @p event_info is @c NULL.
*
* - #EVAS_CALLBACK_IMAGE_UNLOADED: @p event_info is @c NULL.
*
* @note Be careful not to add the same callback multiple times, if
* that's not what you want, because Evas won't check if a callback
* existed before exactly as the one being registered (and thus, call
* it more than once on the event, in this case). This would make
* sense if you passed different functions and/or callback data, only.
*
* Example:
* @dontinclude evas-events.c
* @skip evas_object_event_callback_add(
* @until }
*
* See the full example @ref Example_Evas_Events "here".

* User can create shape objects as well as fill objects and give it to the

* of the objects. enabling reuse of shape objects.
*
* As Evas_Object_Vg is a Evas_Object all the operation that applicable to
* a Evas_Object can be performed on it(clipping , map, etc).
*
* To create any complex vector graphics you can create a hirarchy of shape
* and fill objects and give the hirarchy to Evas_Object which will be
* responsible for drawing and showing on the screen.
*
* As the shape object and fill object (linear and radial gradient) have
* retain mode API, you only have to create it once and set the properties
* and give it to evas_object_vg.
*
* Any change in the property of shape/fill object will automaticaly notified
* to the evas_object_vg which will trigger a redrawing to reflect the change.
*
* To create a vector path, you can give list of path commands to the shape
* object using efl_gfx_shape_path_set() API.
*
* Enabling graphical shapes to be constructed and reused.
*
* Below are the list of feature currently supported by Vector object.
*
* @li Drawing SVG Path.
* You can construct a path by using api in efl_gfx_utils.h
*
* @li Gradient filling and stroking.
* You can fill or stroke the path using linear or radial gradient.
* @see Evas_Vg_Gradient_Linear and Evas_Vg_Gradient_Radial
*
* @li Transformation support for path and gradient fill. You can apply
affin transformation on path object.
