virtual float EvaluateScalar_WithValue ( FTG_EvaluationContext* InContext, const float*const Value, size_t Count )	Most of the time these are the two functions that expressions will need to implement.	Expressions/Maths/TG_Expression_IfThenElse.h
virtual FTG_Texture EvaluateTexture ( FTG_EvaluationContext* InContext )		Expressions/Maths/TG_Expression_IfThenElse.h
virtual FVector4f EvaluateVector_WithValue ( FTG_EvaluationContext* InContext, const FVector4f*const Value, size_t Count )	Evaluate vector only needs to be implemented if there vector handling isn't just a component-wise scalar handling.	Expressions/Maths/TG_Expression_IfThenElse.h
virtual std::vector< FTG_Variant > GetEvaluateArgs ()	If you use the basic structure of variant expression then you'll need to implement this correctly.	Expressions/Maths/TG_Expression_IfThenElse.h
