FMX Line Angle Demo


 A simple demo showing how to create a GUI with FMX to let the user
draw two intersecting lines and then compute and show the angle between
the two lines.
The use has to click on 3 points: the point where the lines
intersect, the point where the first line (red) ends and the point where
the second line (green) ends.
The user interface is updated in real-time following mouse movements. Full
