How do i have to set the BackPriority of the MarkupInfo of a markup to have the Markup background be painted where no highlighter attribute background is?
I want to mark several lines with a special background. But not where the highliter sets backrounds.
Think of a colored layer between the editor backround and the highlighted code/text.
0 is already above the background of the highlighted tokens
and -1 is not visible at all!
