Plot tool for calculating intensity profiles of image markers along a line.
It is assumed that on the parent Graph an ImageMarker is selected. During initialization, a pointer to this marker is stored and the selection is removed. The LineProfileTool adds itself as a full-sized child widget to the Graph's canvas, allowing for fast redraws while selection of the line is in progress. Once the line is selected (mouse button is released), the profile is calculate and displayed, a new LineMarker denoting the selected profile line is added to the Graph and the LineProfileTool deletes itself by setting the Graph's active tool to NULL.
Actually, image analysis doesn't fit terribly well into the Graph framework. A cleaner approach would be to add a new MyWidget subclass (Image?) that operates on a single image, providing things like line profiles, intensity tables and measuring points on scanned graphs (simple g3data-like functionality). There could be facilities for making an Image from an ImageMarker and vice versa (if that's really needed). [ postponed until after the redesign of project handling ]
