Description Mike Wilson CLA 2001-10-11 14:20:48 EDT 
Open a "Find in file" dialog window to find some key word in a java file in 
Eclipse.
   Move the dialog window will leave continuous shadow on the background 
windows, especially
	when we move it slowly. All the windows affected will repaint 
themselves correctly. But the 
	performance is not satisfactory.

		Not me. Suspect this was WT.

		I've been looking at the paint merging code. It seems to only 
handle Canvases.
		Is this reasonable?

	It's pretty dangerous to change the paint policy for an arbitrary 
widget.
	A C++ app should show the same characteristics.  We should investigate
	to see if we are doing something different.

		Need to look at this again after June.

		I really would like to see us do something about this.

The code in paint and resize has been changed to call XCheckIfEvent to detect 
cases which can optimized. The performance is considerably better than it was.
