Hi! Hansel suggested opening another thread for discussing improvements to the algorithms used in xepdmgr for handling the Typing refresh and the combining of rectangles, so here it is.

Right now (xepdmgr 1.0), the daemon just counts the number of pixels in the area to update and depending on whether it's less than a threshold or not (the threshold is #define'd as 1/3 of the iliad screen), it uses the typing refresh or the full refresh.

About the timeout, it waits 0.5seconds from the last update to commit it to the screen (if there is another change while waiting, it resets the timeout and waits 0.5s again).

Any ideas to improve this?
