 * @defgroup Evas_Object_Group_Map UV Mapping (Rotation, Perspecitve, 3D...)
 *
 * Evas allows different transformations to be applied to all kinds of

 *
 * With UV mapping, one maps points in the source object to a 3D space
 * positioning at target. This allows rotation, perspective, scale and
 * lots of other effects, depending on the map that is used.
 *
 * Each map point may carry a multiplier color. If properly
 * calculated, these can do shading effects on the object, producing
 * 3D effects.
 *
 * As usual, Evas provides both the raw and easy to use methods. The
 * raw methods allow developer to create its maps somewhere else,
 * maybe load them from some file format. The easy to use methods,
 * calculate the points given some high-level parameters, such as
 * rotation angle, ambient light and so on.
 *
 * @note applying mapping will reduce performance, so use with
 *       care. The impact on performance depends on engine in
 *       use. Software is quite optimized, but not as fast as OpenGL.

/**
 * @defgroup Evas_Object_Image Image Object Functions
 *
 * Functions used to create and manipulate image objects.
 *
 * Note - Image objects may return or accept "image data" in multiple
 * formats.  This is based on the colorspace of an object. Here is a
 * rundown on formats:
 *
 * EVAS_COLORSPACE_ARGB8888:
 *
 * This pixel format is a linear block of pixels, starting at the
 * top-left row by row until the bottom right of the image or pixel
 * region. All pixels are 32-bit unsigned int's with the high-byte
 * being alpha and the low byte being blue in the format ARGB. Alpha
 * may or may not be used by evas depending on the alpha flag of the
 * image, but if not used, should be set to 0xff anyway.
 *
 * This colorspace uses premultiplied alpha. That means that R, G and
 * B cannot exceed A in value. The conversion from non-premultiplied
 * colorspace is:
 *
 * R = (r * a) / 255; G = (g * a) / 255; B = (b * a) / 255;
 *
 * So 50% transparent blue will be: 0x80000080. This will not be
 * "dark" - just 50% transparent. Values are 0 == black, 255 == solid
 * or full red, green or blue.
 *
 * EVAS_COLORSPACE_YCBCR422P601_PL:
 *
 * This is a pointer-list indirected set of YUV (YCbCr) pixel
 * data. This means that the data returned or set is not actual pixel
 * data, but pointers TO lines of pixel data. The list of pointers
 * will first be N rows of pointers to the Y plane - pointing to the
 * first pixel at the start of each row in the Y plane. N is the
 * height of the image data in pixels. Each pixel in the Y, U and V
 * planes is 1 byte exactly, packed. The next N / 2 pointers will
 * point to rows in the U plane, and the next N / 2 pointers will
 * point to the V plane rows. U and V planes are half the horizontal
 * and vertical resolution of the Y plane.
 *
 * Row order is top to bottom and row pixels are stored left to right.
 *
 * There is a limitation that these images MUST be a multiple of 2
 * pixels in size horizontally or vertically. This is due to the U and
 * V planes being half resolution. Also note that this assumes the
 * itu601 YUV colorspace specification. This is defined for standard
 * television and mpeg streams.  HDTV may use the itu709
 * specification.
 *
 * Values are 0 to 255, indicating full or no signal in that plane
 * respectively.
 *
 * EVAS_COLORSPACE_YCBCR422P709_PL:
 *
 * Not implemented yet.
 *
 * EVAS_COLORSPACE_RGB565_A5P:
 *
 * In the process of being implemented in 1 engine only. This may change.
 *
 * This is a pointer to image data for 16-bit half-word pixel data in
 * 16bpp RGB 565 format (5 bits red, 6 bits green, 5 bits blue), with
 * the high-byte containing red and the low byte containing blue, per
 * pixel. This data is packed row by row from the top-left to the
 * bottom right.
 *
 * If the image has an alpha channel enabled there will be an extra
 * alpha plane after the color pixel plane. If not, then this data
 * will not exist and should not be accessed in any way. This plane is
 * a set of pixels with 1 byte per pixel defining the alpha values of

 *
 * Convenience macro to subclass a Smart Class.
 *
 * This macro saves some typing when writing a Smart Class derived from

 * adhering to the following guidelines.
 *  - @<prefix@>_smart_set_user(): the internal _smart_set function will call
 *    this one provided by the user after inheriting everything from the
 *    parent, which should take care of setting the right member functions
 *    for the class.
 *  - @<prefix@>_parent_sc: pointer to the smart class of the parent. When calling
 *    parent functions from overloaded ones, use this global variable.
 *  - @<prefix@>_smart_class_new(): this function returns the Evas_Smart needed
 *    to create smart objects with this class, should be called by the public
 *    _add() function.
 *  - If this new class should be subclassable as well, a public _smart_set()
 *    function is desirable to fill the class used as parent by the children.
 *    It's up to the user to provide this interface, which will most likely
 *    call @<prefix@>_smart_set() to get the job done.
 *
 * @param smart_name The name used for the Smart Class. e.g: "Evas_Object_Box".
 * @param prefix Prefix used for all variables and functions defined.
 * @param api_type Type of the structure used as API for the Smart Class. Either Evas_Smart_Class or something derived from it.
 * @param parent_type Type of the parent class API.
 * @param parent_func Function that gets the parent class. e.g: evas_object_box_smart_class_get().
