The Point class is used to represent a point/coordinate/vector, for example (1.2mm; 5.6mm) for X=1.2mm and Y=5.6mm.
This class is used to represent ALL coordinates in Symbols, Schematics, Footprints, Layouts and so on. You should never use another coordinate type, like QPoint or QPointF! It's very important to have a consistent coordinate type over the whole project.
A Point object consists always of two Length objects. Basically, this is the only goal of this class, but it will provide also some useful addidional methods.

inlinenoexcept 
Default Constructor.
The object will be initialized with X=Length(0) and Y=Length(0).
