REVISION SUMMARY
  Our pixmap is the size of the number of lines in the document. When
  rendering the pixel for the modified marker we want to take a ratio of
  currentline to lines in the pixmap.
  
  The height of the groove isn't relevant.

TEST PLAN
  Create a 10000 line empty document
  Added some line in the middle
  New line and orange dot appeared in the same place

REPOSITORY
  R39 KTextEditor

BRANCH
  master
