I tried this and I'm still having difficulties. The redisplay
code optimizes drawing. It appears these optimizations make it so the
xwidget glyph draw routine isnt allways called on redisplay. I tried to
work around this by adding a flag to the buffer modify routines. The
idea is, if the flag is set and the widget hasnt been redrawn, then it
should die. So far I havent had any sucess.
