Description
Generates a vector based on the given X and Y 2D coordinates.
There are two Vector overloaded functions. The first one accepts the X and Y coordinates as Single floating-point values, while the second Vector overloaded function accepts the TPointF format 2D coordinates.
To be able to realize a vector transformation using a transformation matrix, the third W coordinate is added. If the W is not explicitly specified, it is assumed to be W = 1.0. The W coordinate value is ignored in all methods that use TVector and are declared inside the FMX.Types unit.
