I think this is impossible to do. Having a stroked object,
transformation *must* change the outline strokes, too, or you get
unstable results. Just think of a square rotated by 45 degrees that
gets scaled by (100,1) to make it extremely broad: Following your
idea, the strokes would no longer be properly connected in the top and
bottom corners because the angle between the square edges changes a
lot (from 90 degrees to almost 180 degrees).
In other words, strokes must always be applied to the final shape. A
transformation matrix must be applied to the object before the
stroking process starts.
What about using `FT_Stroker_ParseOutline' after transformation of the
outline?
