+	Description:	FT - MMI: Wrong trace class 
+	Solution:		changed event traces to function traces because the information content of 
+				this is low for non-MMI people and against TI coding convention.

+      Description:	eZi Text function is not working

+                            such as window, keyboard, timer, etc., are deleted so that the 
+                            current_mfw_element does not point to element that has already been freed.

+	The mfwEorc is made const.The changes will be present both in Color and Golite build .
