* @brief Create a frame widget
*
* @details This widget provides a window like we know it from desktop systems.
*
* @param[in] g The GDisplay to display this window on
* @param[in] fo The GFrameObject structure to initialize. If this is NULL the structure is dynamically allocated.
* @param[in] pInit The initialization parameters
* @param[in] flags Some flags, see notes.
*
* @note Possible flags are: GWIN_FRAME_BORDER, GWIN_FRAME_CLOSE_BTN, GWIN_FRAME_MINMAX_BTN.
* When the close or the minimize/maximize buttons are used, the boarder is automatically invoked.
* @note These frame buttons are processed internally. The close button will invoke a gwinDestroy() which will
* destroy the window itself and EVERY child it contains (also children of children).
*
* @return NULL if there is no resulting widget. A valid GHandle otherwise.
