Needed to draw a rectangle and freehand-line for hilighting

[I_go_r]

For making hilighting in pictures (in screenshots or scanned documents), there are tool needed for drawing rectangle or freehand-line. It`s necessary for underlining some text or outlining some areas of picture. Will be nice if color and thickness of the line will be selectable.
Thanks for great tool!
