+ * @brief Functions that deal with 3D projection of an 2D object.
+ *
+ * Perspective is a graphical tool that makes objets represented in 2D
+ * look like they have a 3D appearance.
+ *
+ * Edje allows us to use perspective on any edje object. This group of
+ * functions deal with the use of perspective, by creating and configuring
+ * a perspective object that must set to a edje object or a canvas,
+ * affecting all the objects inside that have no particular perspective
+ * set already.
