Like for example position the image corner at point (100,100).

Matrix matrix;
matrix.Translate(100.0f, 100.0f);
matrix.RotateAt(30.0f /*angle to rotate*/, PointF(100.0f, 100.0f), MatrixOrderAppend);
graphics.SetTransform(&matrix);
graphics.DrawImage(&img, PointF(0, 0));
graphics.ResetTransform();

whether the wrapped pointer member must be pointing to inner structs/classes? Or the pointer could be pointed to global/namespace level structs/classes?

class Object; // forward declaration.

It may point to anything. Inner or outer, it's a bad practice. It's highly recommended not to use it.
