Detailed Description

vector (magnitude and direction) within a 2D coordinate system.

Point provides support for dealing with vectors as x, y floating point values in 2 dimensional space. A vector is similar to an Offset but can be treated as a magnitude and direction where an Offset can't. The PDG coordinate space starts with the top left corner of the drawing port at Point(0,0) and the bottom left corner at Point( width, height );
