* This structure is filled by caca_get_event() when an event is received.

*
* \li \b CACA_EVENT_NONE: no other field is valid.
*
* \li \b CACA_EVENT_KEY_PRESS, \b CACA_EVENT_KEY_RELEASE: the \e data.key.c
* field is valid and contains either the ASCII value for the key, or
* an \e enum \e caca_key value. If the value is a printable ASCII
* character, the \e data.key.ucs4 and \e data.key.utf8 fields are
* also filled and contain respectively the UCS-4/UTF-32 and the UTF-8
* representations of the character. Otherwise, their content is
* undefined.
*
* \li \b CACA_EVENT_MOUSE_PRESS, \b CACA_EVENT_MOUSE_RELEASE: the
* \e data.mouse.button field is valid and contains the index of the
* mouse button that was pressed.
*
* \li \b CACA_EVENT_MOUSE_MOTION: the \e data.mouse.x and \e data.mouse.y
* fields are valid and contain the mouse coordinates in character
* cells.
*
* \li \b CACA_EVENT_RESIZE: the \e data.resize.w and \e data.resize.h
* fields are valid and contain the new width and height values of
* the \e libcucul canvas attached to \e libcaca.
*
* The result of accessing data members outside the above conditions is
