     <li>IMPROVED/REWORKED: coordinate axis code was refactored</li>
     <li>IMPROVED/REWORKED: zomm/pan by mouse-wheel: now there are modes that support zoomin AND panning by trakpad and mouse-wheel simultaneously! This can only be implemented using heuristics, due to the way that Qt handles track-pad events, but the current solution should at least improve the behaviour seen before. Mainly <code>jkqtpmwaZoomByWheelAndTrackpadPan</code> was introduced into <code>JKQTPMouseWheelActions</code> und is set as default mode: Here JKQTPlotter tries to distinguish the QWheelEvent s sent by an actual mouse wheel and a trackpad.</li>

     <li>NEW/BREAKING CHANGE: data tooltip can now also be shown when "just" moving the mouse (so far this was only possible when dragging the mouse with a button pressed).

 In addition you can build your own palettes as simple lookup-tables of type `JKQTPImageTools::LUTType` (which is a `QVector<QRgb>`) and register them in the system (using `JKQTPImageTools::registerPalette()`). There are several options available for building such a palette:

 3. The palettes so far had steps, but you can also give a series of nodes with positions (on the value axis) and RGB-colors there (e.g. `palsteps2` above) but then linearly interpolate between these by calling:
+
 ```.cpp
     pal=JKQTPBuildColorPaletteLUTLinInterpolate(palsteps2, JKQTPImageTools::LUTSIZE);
 ```

     The resulting LUT is then:   ![imageplot_userpal_2_linear](https://raw.githubusercontent.com/jkriege2/JKQtPlotter/master/screenshots/imageplot_userpal_2_linear.png)
 4. Finally there is a second way of linear interpolation, where linear segments are given for the three color channels separately. To use such a definition, call `JKQTPBuildColorPaletteLUTLinSegments` instead (see documenttaion there).
 
 For each of these options, you finally call `JKQTPImageTools::registerPalette()` to make them known to the system:
