TTransformation is an abstract ancestor for bitmap transformation classes. TTransformation objects are passed as parameter in the Transform function, which actually performs the bitmap transformation. Custom decendants must at least implement ReverseTransformFloat (and TransformFloat, if forward transformation is supported), since this is the top precision level in the transformation system of Graphics32. All decendants must override at least this level, but for optimal performance, it is recommended that the integer and fixed versions are implemented, respectively.
