Testing
-------

This patch solves the xAxis bug from my previous patch and brings new improvements regarding the Altitude vs Time tool.

Now, the bug regarding the Top and Bottom axes is solved. The user can Zoom and Drag the curves without any problem.

The most important improvement I've made over my last AltvsTime patch is the next one: 
Now, the user can get accurate information directly from the curve with a simple Right-Click.
All the user needs to do is to right-click wherever he wants to analyze the curve. A very intuitive information box will show up.
For better and more accurate results regarding the information from the curves I had to recompute the curves with more points. The algorithm searches on the curve the closest point to the mouse click point, so more points on curve means more precision.

Here is another presentation clip that shows the most recent updates I have brought to KStars Altitude vs Time tool:
