Search for
OnSpecialLine Markup
(or OnSpecialLineColor, if it is just background color)

The code in this event should be fast. It will be called many times 
(everytime any part of a line is painted).

So calculate and store the needed info somewhere else, and then in the 
event, only compare the line number with the stored value.
