template<typename T>  
class TTransform2

Support for generalized 2D affine transforms. Implemented as a 2x2 transform followed by translation. In matrix form: [A B 0] [C D 0] [X Y 1]

	Type	Name	Description
		TTransform2 ( const UE::Math::TVector2< VType >& Translation )	Initialize the transform using an identity matrix and a translation.
		TTransform2 ( T UniformScale, const UE::Math::TVector2< VType >& Translation )	Initialize the transform using a uniform scale and a translation.
		TTransform2 ( const TScale2< T >& Scale, const UE::Math::TVector2< VType >& Translation )	Initialize the transform using a 2D scale and a translation.
		TTransform2 ( const TShear2< T >& Shear, const UE::Math::TVector2< VType >& Translation )	Initialize the transform using a 2D shear and a translation.
		TTransform2 ( const TQuat2< T >& Rot, const UE::Math::TVector2< VType >& Translation )	Initialize the transform using a 2D rotation and a translation.
		TTransform2 ( const TMatrix2x2< T >& Transform, const UE::Math::TVector2< VType >& Translation )	Initialize the transform using a general 2x2 transform and a translation.
