Hi!
Attached is xepdmgr v1.9i
Implements the dirty area management using Hansel's proposal of just dividing the screen in blocks and tag the dirty ones (see start of this thread O

).
This fixes the problems where xepdmgr was doing a Typing refresh when a full refresh was better (most of the screen changed). Now xepdmgr does a Typing refresh when only part of the screen is changed and a Ful one when almost all the screen has changed.
Enjoy!
