Summary:
Developer can use this API for the case when he/she wants ctxpopup not to hide
automatically when parent of ctxpopup is resized or language is changed.
Default value of "disabled" is EINA_FALSE. So if user sets "disabled" EINA_TRUE
and parent size changes, ctxpopup recalculates its size and position.
Since size of bg is set when setting parent only, it should be resized again.
